[PATCH] resource: change MEMATTRS_NORMAL to MEMATTR_WB

[PATCH] resource: change MEMATTRS_NORMAL to MEMATTR_WB

[Ahmad Fatoum]

Other EFI loaders (EDK-II, U-Boot) only set WB (Write-Back) for normal
memory. Let's follow suit for barebox.

This introduces no functional change yet, as these attributes will only
be put to use with the incoming EFI loader support.
