p54: fix powerpc gcc warnings
My commit "p54: parse output power table" introduced the following compiler warnings for powerpc-allmodconfig eeprom.c: In function 'p54_get_maxpower': eeprom.c:291 warning: comparison of distinct pointer types lacks a cast eeporm.c:292 warning: comparison of distinct pointer types lacks a cast eeprom.c:293 warning: comparison of distinct pointer types lacks a cast eeprom.c:294 warning: comparison of distinct pointer types lacks a cast This patch fixes those by using max_t(u16 which forces a type cast.
