[U-Boot] [PATCH 1/1] x86: efi_loader: Fix invalid address return from efi_alloc()

This issue can be seen on 32bit operation when one of E820_RAM type entries is greater than 4GB memory space. The efi_alloc() finds a free memory in the conventional memory which is greater than 4GB. But, it does type cast to 32bit address space and eventually returns invalid address.
