Subject: [PATCH 04/14] staging: r8188eu: merge EFUSE_ShadowMapUpdate with its caller

Merge the EFUSE_ShadowMapUpdate function into ReadAdapterInfo8188EU, which
is the only caller.

Merging the two functions makes it clearer that eeprom->efuse_eeprom_data
is in fact a temporary buffer that stores info read from efuses.
