sd: sdhci: Implement basic vendor specific register support
The Linux kernel's IMX code now uses vendor specific commands.
This results in endless warnings when booting the Linux kernel.
sdhci-esdhc-imx 2194000.usdhc: esdhc_wait_for_card_clock_gate_off:
card clock still not gate off in 100us!.
Implement support for the vendor specific command implemented in IMX hardware
to be able to avoid this warning.
