Phong Hoang 31fc50cd93 clocksource/drivers/sh_cmt: Fix wrong setting if don't request IRQ for clock source channel 
[ Upstream commit be83c3b6e7 ]

If CMT instance has at least two channels, one channel will be used
as a clock source and another one used as a clock event device.
In that case, IRQ is not requested for clock source channel so
sh_cmt_clock_event_program_verify() might work incorrectly.
Besides, when a channel is only used for clock source, don't need to
re-set the next match_value since it should be maximum timeout as
it still is.

On the other hand, due to no IRQ, total_cycles is not counted up
when reaches compare match time (timer counter resets to zero),
so sh_cmt_clocksource_read() returns unexpected value.
Therefore, use 64-bit clocksoure's mask for 32-bit or 16-bit variants
will also lead to wrong delta calculation. Hence, this mask should
correspond to timer counter width, and above function just returns
the raw value of timer counter register.

Fixes: bfa76bb12f ("clocksource: sh_cmt: Request IRQ for clock event device only")
Fixes: 37e7742c55 ("clocksource/drivers/sh_cmt: Fix clocksource width for 32-bit machines")
