Fix detection of Philips RTC/NVRAM when MaybeIIC is in use

Detail:
  s/PMF/i2cutils - Although the code will detect the Philips RTC correctly, it was failing to set the device size in R4, causing CMOS RAM to be misread. This change fixes that.
Admin:
  Tested in IOMD HAL build on development version of RPCEmu.
