zynqmp: tapdelays: Remove usage of SD0_OTAPDLYENA and SD1_OTAPDLYENA
This patch removes usage SD0_OTAPDLYENA and SD1_OTAPDLYENA bits.
This bits have impact on functionality of RTL due to one issue in
RTL where SD0_OTAPDLYENA (Bit 6) has been wrongly connected to both
SD0 and SD1 instances. This makes SD1_OTPDLYENA redundant. Also, these
signals are not used anywhere in silicon and hence there is
really no need to set these bits.

AXI master interface in CEVA AHCI controller requires two unique
Write/Read ID tags per port. This is because, ahci controller uses
different AXI ID[3:0] bits for identifying non-data transfers(like
reading descriptors, updating PRD tables, etc) and data transfers
(like sending/receiving FIS).To make SMMU work with SATA we need to
add correct SMMU stream id for SATA. SMMU stream id for SATA is
determined based on the AXI ID[1:0] as shown below
SATA SMMU ID = <TBU number>, 0011, 00, 00, AXI ID[1:0]
Note: SATA in ZynqMp uses TBU1 so TBU number = 0x1, so
SMMU ID = 001, 0011, 00, 00, AXI ID[1:0]
Since we have four different AXI ID[3:0] (2 for port0 & 2 for port1
as said above) we get four different SMMU stream id's combinations
for SATA. These AXI ID can be configured using PAXIC register.
In this patch we assumed the below AXI ID values
Read ID/ Write ID for Non-Data Port0 transfers = 0
Read ID/ Write ID for Data Port0 transfers = 1
Read ID/ Write ID for Non-Data Port1 transfers = 2
Read ID/ Write ID for Data Port1 transfers = 3
Based on the above values,SMMU stream ID's for SATA will be 0x4c0 &
0x4c1 for PORT0, 0x4c2 & 0x4c3 for PORT1. These values needed to be
added to iommus dts property. This patch does the same.

libfdt: Correct fdt handling of overlays without fixups and base trees without symbols
The fdt_overlay_apply() function purports to support the edge cases where
an overlay has no fixups to be applied, or a base tree which has no
symbols (the latter can only work if the former is also true). However it
gets it wrong in a couple of small ways:
* In the no fixups case, it doesn't fail immediately, but will attempt
fdt_for_each_property_offset() giving -FDT_ERR_NOTFOUND as the node
offset, which will fail. Instead it should succeed immediately, since
there's nothing to do.
* In the case of no symbols, it again doesn't fail immediately. However
if there is an actual fixup it will fail with an unexpected error,
because -FDT_ERR_NOTFOUND is passed to fdt_getprop() when attempting to
look up the symbols. We should instead return -FDT_ERR_NOTFOUND
directly.
Both of these errors lead to the code returning misleading error codes in
failing cases.
