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.

Embedded flash can have user signature area on SAMv7. This is a 512
bytes large page whose data are not erased by asserting ERASE pin or by
software ERASE command.
This commit adds arch to board interface for this area. It is possible
to perform read, write and erase operation. SAMV7_USER_SIGNATURE option
has to be set in the configuration.

The definition of nxsched_process_cpuload_ticks uses clock_t, which is
portable across uint32_t and uint64_t timers, and works if CONFIG_SYSTEM_TIME64 is
defined.
DAC driver uses CONFIG_DAC_FIFOSIZE, but this is not configurable
from Kconfig. This adds the missing option and allows to set DAC
FIFO size from the configuration.

By default U(S)ART clocks are enabled in sam_lowput.c but
configuration check from sam_config.h may override USART configuration
and prevent clocks from been enabled.
This commit fix inconsistency in U(S)ART pinmux and clock configuration

In "psock_send_eventhandler",when retransmit count bigger TCP_MAXRTX nuttx will set release wrb. But before this it will also set "conn->tx_unacked = 0" if we only retransmit one packet(conn->tx_unacked == sent),and In func "tcp_timer" only "conn->tx_unacked > 0" will close the tcp conn. So app will never close if nuttx retransmit over max timers.

This provides a capable bootloader that may be run from OCRAM.
The OCRAM contains regions that are always zero, so the linker
file avoids those with best effort.
iMX9 infrastructure expects:
- 0x20480000 (Start of OCRAM, AHAB)
- 0x2049a000 (NuttX or SPL)
- 0x204e0000 (ARM Trustzone, not used)
When started from SD-card, the offsets are:
- 0x1f000 with AHAB
- 0xa000 without AHAB
