This commit fills the void for current OpenWrt installations which will
be still on old bootloader version even after "x86: add bootloader
upgrade on sysupgrade", since it performs bootloader upgrade only on
sysupgrade. To keep all OpenWrt deploynents on the same GRUB version,
add preinit hook, which will perform upgrade of the bootloader on first
boot after sysupgrade.
It's temporary solution and should be deleted, when the first release
including this hook will no longer be supported by OpenWrt team.
We can assume that all installations should be on current bootolader
version and from there sysupgrade routine will be sufficient.

Currently bootloader always stays on the same version as when first
written to boot medium (not true if partition layout changed, which will
trigger sysupgrade process to write full disk image). That creates
inconveniences as it always stays with same features or/and bugs. Users
wishing to add support to additional modules or new version, would need
to write the whole image, potentially destroying previous system
configuration. To fix these, this commit adds additional routine to
sysupgrade which upgrades unconditionally the bootloader to the latest
state provided by OpenWrt.

tools/pkg-config: Replace with pkgconf
pkgconf is a newer, actively maintained implementation of pkg-config that
supports more aspects of the pkg-config file specification and provides a
library interface that applications can use to incorporate intelligent
handling of pkg-config files into themselves (such as build file
generators, IDEs, and compilers). Through its pkg-config compatibility
interface (activated when it is run as "pkg-config"), it also can
completely replace the original implementation.
It is also lighterweight and does not require glib2, as pkg-config does.
On other distros, pkgconf is symlinked to pkg-config. For simplicity here,
it is renamed to pkg-config.real, as in the original package.
Initial results have been positive. As before, pkgconf works as long as

This adds the neon based implementations of AES & SHA256.
For AES, according to the kernel config help:
Use a faster and more secure NEON based implementation of AES in CBC,
CTR and XTS modes.
Bit sliced AES gives around 45% speedup on Cortex-A15 for CTR mode
and for XTS mode encryption, CBC and XTS mode decryption speedup is
around 25%. (CBC encryption speed is not affected by this driver.)
This implementation does not rely on any lookup tables so it is
believed to be invulnerable to cache timing attacks.
...
The observed speedups on ipq40xx are more modest: speedup is around 20%
for CTR mode and for XTS mode encryption, CBC and XTS mode decryption
speedup is around 10%. Measurements were made using tcrypt, with
1024-bytes blocks for CTR & CBC, and 4096-bytes for XTS.
The aes-neon-bs driver uses a fallback for CBC encryption; that fallback
could be either the generic driver written in C, or the scalar arm-asm
one. Even though aes-arm is 1.9% slower, it is more resilient to timing
attacks (the reason for being slower), so it is being included here.
The neon sha256 module increases performance over the generic module by
33%.

The introduction of ebf0d8dadeca ("ath79: add new ar934x spi driver")
made the SPI memory unusable on devices with very high spi-max-frequency
(104 MHz).
Here's how the actual clock is calculated: (AHB_CLK/((CLOCK_DIVIDER+1)*2))
where AHB_CLK is a fixed clock (e.g. 200MHz on AR9331) and CLOCK_DIVIDER
is the parameter we can set. Highest clock according to this formula is
AHB_CLK/2 (100MHz, but that didn't work in device tests).
The next possible value is AHB_CLK/4 (50MHz). Speeds between 50 MHz and
100 MHz will be rounded down, so using values higher than 50 MHz does
not provide any benefit.
Consequently, this patch reduces spi-max-frequency for all devices with
values higher than 50 MHz to 50 MHz (effectively, this only affects
devices with 104 MHz before this patch).
Tested on GL.inet GL-AR150:
Boot fails with 104 MHz but is successful with both 50 MHz and 80 MHz
(fast-read), where the latter two yield identical read speeds.
