[U-Boot] [PATCH v4 1/2] lib: crc32: mark function crc32() as __efi_runtime

[Heinrich Schuchardt]

The function crc32() is needed by the EFI subsystem at runtime. So it has
to be linked into the runtime section together with all dependencies.

Eliminate empty defines local and ZEXPORT.

Mark variables as static which are not exported.

v4:
	put all relevant functions into the runtime code section
	put none into the runtime data section
v3
	new patch
