bootm: fix boot failure from compressed image for IH_OS_EFI

The bootm command can handle the compressed image, but current
code fails to boot from it.

## Loading kernel (any) from FIT Image at a8000000 ...
<snip>
Compression: gzip compressed
Data Start: 0xa80000d4
Data Size: 10114520 Bytes = 9.6 MiB
Architecture: AArch64
OS: EFI Firmware
Load Address: 0x90000000

<snip>
Uncompressing Kernel Image to 90000000
## Transferring control to EFI (at address a80000d4) ...
Booting <NULL>
Not a PE-COFF file
Loading image failed

To take care of the compressed image, the load address needs
to be passed instead of the original compressed image address.
