lib: bidram: add 4GB+ memory size support

- On ARMv7: LPAE seems to be not friendly that brings a lot of
compile errors.

- On ARMv8: MMU translate table is static defined by mem_map[]
and max 4GB as usual. It is not created dynamically according
to real memory size, that is different from ARMv7.

- 4GB memory is enough for U-Boot on both ARMv7 an ARMv8.

Considering all that, we decide to make max 4GB size to be visiable
for U-Boot, but still pass the real available memory size to kernel
by bidram_fixup() called at late before fixup "/memory" node.

lib: sysmem: optimise alloc policy

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.

lib: sysmem: support avb android memblk sysmem alloc

Because avb android image usually needs a large memory buffer,
always alloc avb android memblk right after U-Boot stack is a
better choice to avoid memblk overlap with others.

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