mmc: use core clock frequency in bcm2835 sdhost
In raspberrypi-firmware 7fdcd00e00a42a1c91e8bd6f5eb8352fe9358557 and
later start.elf now sets the EMMC clock to 200 MHz.
According to Phil Elwell in
https://github.com/raspberrypi/firmware/issues/953
the SDHost controller shares the core/VPU clock and doesn't use
the EMMC clock.
Use the core clock id when determining the frequency to allow
U-Boot to work with recent versions of raspberrypi-firmware.
Otherwise U-Boot hangs at:
U-Boot 2018.03 (Mar 14 2018 - 20:36:00 +1100)
DRAM: 948 MiB
RPI 3 Model B (0xa02082)
MMC: mmc@7e202000: 0, sdhci@7e300000: 1
