MCP794XX supports digital trimming that periodically adds or subtracts
clock cycles, resulting in small adjustments in the internal timing.
This way inaccuracies of clock source can be compensated.
This commit adds option to set the trimming register for MCP794XX.

This commit adds configuration option CONFIG_MCP794XX_DATETIME_UTC.
If set, the datetime is stored in UTC instead of local time. The
default value is kept at local time to keep backwards compatibility
with devices currently using the RTC.

Remove TIME_EXTENDED option to more conform C standard
Note: the code/data size increment is small
arch/arm/src/tiva/cc13xx: Trim code now kind of looks like NuttX code. But does not yet compile.
arch/arm/src/tiva/cc13xx: The first few, feeble steps toward getting the overall trim files compatible with the requirements of the NuttX coding standard.
arch/arm/src/tiva/cc13xx: Replace last of TI hardware access macros with NuttX hardware access macros.
arch/arm/src/tiva/cc13xx: Change TI HWREGB to NuttX getreg8 or putreg8 in trim logic.
arch/arm/src/tiva/cc13xx: Change TI HWREGBITW to NuttX getreg32/putreg32 sequence in trim logic.
arch/arm/src/tiva/hardware/cc13x2_cc26x2/cc13x2_cc26x2_ddi0_osc.h: Completes the DDIO OSC header file.
cc13x2_cc26x2/cc13x2_cc26x2_ddi0_osc.h: Updated, but still not finished.
arch/arm/src/tiva/hardware/cc13x2_cc26x2/cc13x2_cc26x2_ddi0_osc.h: Add DDI0 OSC header file. Still a work in progress. Does not yet conform to the NuttX coding standard.
Change _M and _S to _MASK and _SHIFT.
Some minor improvements.
Clean up typos in some comments.
