media: atomisp: gc0310: Fix power on/off sleep times

Reduce the unnecessary long msleep(100) done on stream start to 10 ms and
move this to gc0310_resume() so that it is also done on the initial
power-up done by gc0310_detect(), which should fix gc0310_detect()
sometimes failing.

While at it switch the sleeps from msleep() / usleep_range() to fsleep().
