feat(mmc): manage SD Switch Function for high speed mode

On SD-cards, Switch Function Command (CMD6) is used to switch
functions, like setting High Speed mode. It is useful for high capacity
cards to double frequency (from 25MHz by default to 50MHz).
If the SD-card is High Capacity, a CMD6 is issued after filling the
device information. If High Speed mode is supported and the switch is
OK, then the max_bus_freq can be set to 50MHz. The driver set_ios()
function should then be called to update peripheral configuration,
especially clock prescaler.

fix(mmc): remove broken, unsecure, unused eMMC RPMB handling

Replay-protected memory block access is enabled by writing 0x3
to PARTITION_ACCESS (bit[2:0]). Instead the driver is using the
first boot partition, which does not provide any playback protection.
Additionally, it unconditionally activates the first boot partition,
potentially breaking boot for SoCs that consult boot partitions,
require boot ack or downgrading to an old bootloader if the first
partition happens to be the inactive one.

Also, neither enabling or disabling the RPMB observes the
PARTITION_SWITCH_TIME. As there are no in-tree users for these
functions, drop them for now until a properly functional implementation
is added. That one will likely share most code with the existing boot
partition switch, which doesn't suffer from the described issues.
