[POWERPC] PS3: Cleanup of os-area.c
Minor cleanup of the PS3 file os-area.c:
o Correct file text header.
o Add type names enum os_area_ldr_format, enum os_area_boot_flag,
enum os_area_ctrl_button.
o Change struct os_area_header.magic_num type to u8.
o Add preprocessor macro SECONDS_FROM_1970_TO_2000.
