To implement the EFI_SYSTEM_TABLE_POINTER we need 4 MiB aligned
memory.
On the sandbox LMB uses addresses relative to the start of a page aligned
RAM buffer allocated with mmap(). This leads to a mismatch of alignment
between EFI which uses pointers and LMB which uses phys_addr_t.
Ensure that the RAM buffer used for LMB is 4 MiB aligned.
Provide a unit test for efi_alloc_aligned_pages() verifying this alignment.
Do not overwrite RAM size in dram_init().
v2:
rename define CFG_SYS_SDRAM_ALIGN to SB_SDRAM_ALIGN

sandbox: fix dram_init()
sandbox: align LMB memory
test: unit test for efi_alloc_aligned_pages()
