Since we now have driver for the SDHCI VQMMC LDO needed
for I/0 voltage levels lets introduce the necessary node for it.

Hi,
Is there an issue with the patch preventing the review?

The actual hardware block where this register is found is the "TCSR"
which is 0x01947000 of size 0x21000 - making this the register at offset
0x11000.

Perhaps it would have been better represented as a simple-mfd with this
regulator as a child node thereof.


That said, this has been sitting long enough, so I'll merge it as is and
we can rework it once we need more pieces of tcsr.

Thanks,
Bjorn

Thanks,
I was unaware that it is part of TCSR as I don't have datasheets
and this was ported from multiple versions of the downstream driver.
