The 0x0 address is usually allocated by 32-bit uncompressed kernel
and this alloc action is just a peek. Due to LMB core doesn't support
alloc at 0x0 address, we have to alloc the memblk backword a few bytes.

This patch is mainly to avoid fail message from sysmem/LMB.

lib: sysmem: optimise alloc policy

- Allow request region alloc within the first invisiable region reserved by
bidram when request region has flags M_ATTR_IGNORE_INVISIBLE. This is a
workaround for some firmware memory layout, eg: on RK3308-AArch32, the ATF
region is 0~1M(same as RK3308-AArch64), but the kernel would like to alloc
at 0x00058000.

- Always make kernel reserved-memory alloc successfully and check overlap
with invisible and sysmem allocated regions in sysmem_overflow_check()
before bootm. This makes alloc policy more easier.

Because avb android image usually needs a large memory buffer,
always alloc avb android memblk right after U-Boot stack is a

Since we have overflow protect magic for U-Boot stack, so we add
a pad(4KB) between them.
