When we're trying to find the base of ram, if we start with GRUB_UINT_MAX
(0xffffffff on all platforms) and always use min(), that means we eventually
decide that the base of ram is GRUB_UINT_MAX, which is lower than our first
memory address, and thus our allocation of the initramfs, which specifies this
value as the maximum possible address it can be at, fails.
This patch changes it to start at GRUB_EFI_MAX_USABLE_ADDRESS, which is always
at least 0xffffffff on 32-bit platforms and at least 0x7ffffffffffffff on
64-bit platforms. Additionally, this adds a requirement that the memory we
choose is actually /allocatable/ conventional memory, not merely
write-combining. On this machine that means we wind up with an allocation
around 0x4392XXXXXX, which is a reasonable address.
This also changes grub_efi_allocate_pages_real() so that if 0 is allocated, it
tries to allocate again starting with the same max address it did the first
time, rather than interposing GRUB_EFI_MAX_USABLE_ADDRESS there, so that any
per-platform constraints on its given address are maintained.
