[PATCH v6 0/3] clocksource/drivers/atcpit100: Add andestech atcpit100 timer

[Greentime Hu <green.hu@gmail.com>]

ATCPIT100 is often used on the Andes architecture,
This timer provide 4 PIT channels. Each PIT channel is a
multi-function timer, can be configured as 32,16,8 bit timers
or PWM as well.

For system timer it will set channel 1 32-bit timer0 as clock
source and count downwards until underflow and restart again.

It also set channel 0 32-bit timer0 as clock event and count
downwards until condition match. It will generate an interrupt
for handling periodically.

Changes in v6:
 - To select TIMER_OF in drivers/clocksource/Kconfig instead of arch/nds32/Kconfig
 - Refine Kconfig
 - Update license format to SPDX-License-Identifier
