There's a number of drivers (e.g. dw_mmc, meson-gx, mmci, sunxi) using
the same mechanism and a private flag vqmmc_enabled to deal with
enabling/disabling the vqmmc regulator.
Move this to the core and create new helpers mmc_regulator_enable_vqmmc
and mmc_regulator_disable_vqmmc.

mmc: core: Allow invalid regulator in mmc_regulator_set_ocr()2023-03-23T10:30:19ZHeiner Kallweit2023-02-27T21:02:23Zurn:sha1:4b4b7ac73704bfa796d2be6b96cb9072f7298861
Basically all host drivers use code like this:
if (!IS_ERR(mmc->supply.vmmc))
mmc_regulator_set_ocr(mmc, mmc->supply.vmmc, 0)
Move the IS_ERR() check to mmc_regulator_set_ocr() to simplify host driver
code.

mmc: core: Add missing documetation for 'mmc' and 'ios'2020-07-13T10:18:25ZLee Jones2020-07-01T12:46:50Zurn:sha1:33fc1ebe509ad761937434ce43e1552ce50047ce
Remainder of the kerneldoc descriptions look present and correct.
Fixes the following W=1 kernel build warnings:
drivers/mmc/core/regulator.c:178: warning: Function parameter or member 'mmc' not described in 'mmc_regulator_set_vqmmc'
drivers/mmc/core/regulator.c:178: warning: Function parameter or member 'ios' not described in 'mmc_regulator_set_vqmmc'

mmc: core: Return 1 from mmc_regulator_set_vqmmc() if switch skipped2020-05-28T09:20:58ZMarek Vasut2020-04-16T16:36:48Zurn:sha1:17a0751e60b123ce1a266155abf72acd936b7ecc
Adjust mmc_regulator_set_vqmmc() to return 1 if the voltage switch was
skipped because the regulator voltage was already correct. This allows
drivers to detect such condition and possibly skip various voltage
switching extras.

mmc: core: Convert mmc_regulator_get_ocrmask() to static2019-02-25T14:20:58ZUlf Hansson2019-02-13T17:42:06Zurn:sha1:3958790e673244ec3b0c62197b7372af303f1351
The only left user of mmc_regulator_get_ocrmask() is the mmc core itself.
Therefore, let's drop the export and turn it into static.

mmc: core: Move regulator helpers to separate file2019-02-25T14:20:58ZUlf Hansson2019-02-13T17:10:37Zurn:sha1:de13d5a44e61366ab5b75c111449ca284b6e3f5d
The mmc regulator helper functions, are placed in the extensive core.c
file. In a step towards trying to create a better structure of files,
avoiding too many lines of code per file, let's move these helpers to a new
file, regulator.c.
Moreover, this within this context it makes sense to also drop the export
of mmc_vddrange_to_ocrmask(), but instead let's make it internal to the mmc
core.
