For eSDHC, power supply is through peripheral circuit.
Some eSDHC versions have value 0 of the bit but that
does not reflect the truth. 3.3V is common for SD/MMC,
and is supported for all boards with eSDHC in current
u-boot. So, make 3.3V is supported in default in code.
CONFIG_FSL_ESDHC_VS33_NOT_SUPPORT can be enabled if
future board does not support 3.3V.
This is also a fix-up for one previous patch, which converted
to use IS_ENABLED() for CONFIG_SYS_FSL_MMC_HAS_CAPBLT_VS33
that is not a Kconfig option.
Fixes: 52faec3182 ("mmc: fsl_esdhc: replace most #ifdefs by IS_ENABLED()")

the Kconfig logic slightly to get the functional dependencies of DM_MMC

Until now, the Octeontx MMC driver did only support the ARM Octeon
TX/Tx2 platforms. This patch adds support for the MIPS Octeon platform
to this driver. Here a short summary of the changes:
- Enable driver compilation for MIPS Octeon, including the MMC related
header file
- Reorder header inclusion
- Switch to using the clk framework to get the input clock
- Remove some functions for MIPS Octeon, as some registers don't
exist here

When eSDHC operates at 3.3v, damage can accumulate in an internal
level shifter at a higher than expected rate. The faster the interface
runs, the more damage accumulates. This issue now is found on LX2160A
eSDHC1 for only SD card.
The hardware workaround is recommended to use an on-board level shifter
that is 1.8v on SoC side and 3.3v on SD card side.
For boards without hardware workaround, this option could be enabled,
ensuring 1.8v IO voltage and disabling eSDHC if no card.
This option assumes no hotplug, and u-boot has to make all the way to
to linux to use 1.8v UHS-I speed mode if has card.
If you do not want the workaround for better user experience, of course
you can choose to not select it running eSDHC in unsafe mode.

The fsl_esdhc driver was for Freescale eSDHC on MPC83XX/MPC85XX
initially. The later QoriQ series PowerPC processors (which were
evolutions of MPC83XX/MPC85XX), QorIQ series ARM processors, and
i.MX series processors were using this driver for their eSDHCs too.
For the two series processors, the eSDHCs are becoming more and
more different. We should have split it into two drivers, like them
(sdhci-of-esdhc.c/sdhci-esdhc-imx.c) in linux kernel.
This patch is just to create a fsl_esdhc_imx driver which is a copy
of fsl_esdhc driver for i.MX processors. We will convert i.MX processors
to use fsl_esdhc_imx, and clean up the two drivers separately in the

to overcome limitations in their respective DMA implementation.
This moves the configuration to Kconfig and makes it user-selectable

it unconditionally from their respective Kconfig (see follow-up
patches).
