mmc: fsl_esdhc: convert to CONFIG_FSL_ESDHC_VS33_NOT_SUPPORT
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: 52faec31827e ("mmc: fsl_esdhc: replace most #ifdefs by IS_ENABLED()")
