staging: rtl8188eu: Rename rtl8188e_EFUSE_GetEfuseDefinition()

Rename rtl8188e_EFUSE_GetEfuseDefinition() to EFUSE_GetEfuseDefinition()
and remove original EFUSE_GetEfuseDefinition() function,
so that driver can call rtl8188e_EFUSE_GetEfuseDefinition() directly
without going through EFUSE_GetEfuseDefinition().
