EMMC and SDIO already have these clock-ids (still unused) only sdmmc is
missing them, so fix that.

Some IPs, such as NAND, EMMC, SDIO and SDMMC need clock of 50% duty
cycle, divfree50 can generate clock of 50% duty cycle even in odd
value divisor.

The clocks in the px30 critical clock section are from the regular cru not
the pmucru, so move them to the correct place.

Video-In and -Out interconnect clocks need to stay on all the
time for the peripheral to work and we do not model the actual
interconnect at this point. So mark them as critical for now.

Make this clock a real critical clock, so that writes to the usbphy grf
always succeed.
