LoongArch: Adjust boot & setup for 32BIT/64BIT

Adjust boot & setup for both 32BIT and 64BIT, including: efi header
definition, MAX_IO_PICS definition, kernel entry and environment setup
routines, etc.

Add a fallback path in fdt_cpu_clk_init() to avoid 0MHz in /proc/cpuinfo
if there is no valid clock freq from firmware.
