media: i2c: mt9m114: use fsleep() in place of udelay()

With clang-16, building without COMMON_CLK triggers a range check on
udelay() because of a constant division-by-zero calculation:

ld.lld: error: undefined symbol: __bad_udelay
>>> referenced by mt9m114.c
>>>               drivers/media/i2c/mt9m114.o:(mt9m114_power_on) in archive vmlinux.a

In this configuration, the driver already fails to probe, before
this function gets called, so it's enough to suppress the assertion.

Do this by using fsleep(), which turns long delays into sleep() calls
in place of the link failure.

This is probably a good idea regardless to avoid overly long dynamic
udelay() calls on a slow clock.
