[U-Boot] [U-Boot,v2,1/3] efi: Fix truncation of constant value

[Alexander Graf]

> Starting with commit 867a6ac86dd8 ("efi: Add start-up library code"),
> sparse constantly complains about truncated constant value in efi.h:
> 
> include/efi.h:176:35: warning: cast truncates bits from constant value (8000000000000000 becomes 0)
> 
> This can get quite noisy, preventing real issues to be noticed:
> 
> $ make defconfig
> *** Default configuration is based on 'sandbox_defconfig'
> $ make C=2 -j12 2>&1 | grep truncates | wc -l
> 441
> 
> After the patch is applied:
> $ make C=2 -j12 2>&1 | grep truncates | wc -l
> 0
> $ sparse --version
> v0.5.2
> 
> Following the suggestion of Heinrich Schuchardt, instead of only
> fixing the root-cause, I replaced the whole enum of _SHIFT values
> by ULL defines. This matches both the UEFI 2.7 spec and the Linux
> kernel implementation.
