Detail:
  s/PMF/osword - Migrate the 2012 RTC fix from the HAL branch to the Cortex branch, plus apply similar fix to the code that handles HAL RTC devices (via new YearLOIsGood flag)
  s/PMF/i2cutils - Update HAL RTC year handling to correctly treat YearLO as either 2-bit int or 2-digit BCD
  hdr/RTCDevice - Add YearLOIsGood flag, revise NeedsYearHelp description
Admin:
  Tested on rev C2 beagleboard. Code seems to behave as intended.


Version 5.35, 4.79.2.98.2.21. Tagged as 'Kernel-5_35-4_79_2_98_2_21'

Detail:
  HAL kernels (on the Cortex branch at least) now support HALDevice-based RTCs. If the kernels own RTC code is disabled or fails to detect an RTC, then after HAL_InitDevices is called the HALDevice list will be scanned for any HAL-resident RTC devices.
  Additionally, the RTCSupport flag (in Hdr:Machine.Machine), which was previously TRUE for all HAL kernels, can now be set to FALSE in HAL kernels to disable the kernels own IIC RTC code. This allows the unwanted legacy RTC code to be disabled for machines which are known to use HAL RTCs instead.
  hdr/RTCDevice - new header describing data structures used for HAL RTC device
  hdr/HALDevice - added RTCDevice device type, IIC serial bus type
  hdr/KernelWS - upgraded RTCFitted from a 1 byte field to 4 byte. It now stores either a null value (for no RTC), a value <2048 for an IIC RTC address, or a value >= 2048 for a RTCDevice ptr
  Makefile - added header export of hdr/RTCDevice
  s/GetAll - include hdr/RTCDevice
  s/NewReset - initialise HAL RTC after HAL_InitDevices if required
  s/PMF/i2cutils, s/PMF/osinit, s/PMF/osword - modifications to allow use of HAL RTC (and disallow use of builtin IIC RTC)
