[PATCH 1/3] loongarch: Call arch_mem_init() before platform_init() in the init sequence

The platform_init() function which is called during device bootup
contains a few calls to memblock_alloc().
This is an issue because these allocations are done before reserved
memory regions are set aside in arch_mem_init().
This means that there is a possibility for memblock to allocate memory
from any of the reserved memory regions.

Hence, move the call to arch_mem_init() to be earlier in the init
sequence so that all reserved memory is set aside before any allocations
are made with memblock.
