[PATCH v2] xen/arm: efi-boot misra rule 4.1 fix

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

We have 3 violations of MISRA C Rule 4.1 ("Octal and hexadecimal escape
sequences shall be terminated") in xen/arch/arm/efi/efi-boot.h. Fix them
and take the opportunity to declare them as static const __initconst and
improve the style.

Signed-off-by: Stefano Stabellini <stefano.stabellini@xxxxxxx>

Changes in v2:
- add static const __initconst
- add blank newline for style
