Per SD specification physical layer v4.0, section 3.9.4, it
says "UHS-I supports only 4-bit mode. Host shall select 4-bit
mode by ACMD6. However mmc_sd_init_uhs_card() still go ahead
to initialize the cards anyway, whether card or host won't
support 4-bit mode.
This breaks the platforms which only support 1-bit mode but
with a UHS-I card inserted, as all the tuning process is broken
due to this. Alternatively, we should check the return value from
mmc_set_bus_width to see if host could finish the request to switch
the bus with on its side. But that needs more thing to do than this
patch that just bails out early to try to use high speed mode if 4-bit
mode isn't available for whatever reason. And this patch could also
fix the same problem for sdio since R4_18V_PRESENT won't be set for
ocr when mmc_sdio_init_card() finds mmc_host_uhs() is false.
Note that This patch doesn't keep the checking of card->scr.sda_spec3
and comparing card->scr.bus_widths with SD_SCR_BUS_WIDTH_4 within
mmc_sd_init_uhs_card since if the sd cards response with SD_ROCR_S18A,
it definitely support UHS-I mode, which implicitly means these checks
are always true.

(cherry picked from https://patchwork.kernel.org/patch/10241773/)
Per SDIO Simplified Specification V3, section 3.1.2, A host that
supports UHS-I sets S18R to 1 in the argument of CMD5 to request a
change of the signal voltage to 1.8V. If the card supports UHS-I and
the current signal voltage is 3.3V, S18A is set to 1 in the R4 response.
If the signal voltage is already 1.8V, the card sets S18A to 0 so that
host maintains the current signal voltage. UHS-I is supported in SD mode
and S18A is always 0 in SPI mode.
For the current code, if the signalingvoltage is fixed 1.8v, so
the card will set S18A to 0 for rocr and thus we would clear the
R4_18V_PRESENT from ocr, which make core won't try to use uhs mode.
To fix it, we expect sdio_read_cccr would fail if the uhs mode won't
work at all. Note that it's interesting that some sdio cards still
response S18A even the voltage is fixed to 1.8v and the CMD11 will
also accepted and finish enabling UHS mode successfully.I guess this
is why folks didn't notice this problem. Anyway, fix it.

RK805 is one of Rockchip PMICs family, it has 2 output only GPIOs.
This driver is also designed for other Rockchip PMICs to expend.
Different PMIC maybe have different pin features, for example,
RK816 has one pin which can be used for TS or GPIO(input/out).
The mainly difference between PMICs pins are pinmux, direction
and output value, that is 'struct rk805_pin_config'.

Phase calculation should be based on the clock rate of these clk,
which inherits the clock rate from their parents. If the parent
goes wrong, it would be orphan node leading all the clk rate to
be zero. This breaks the normal tuning process whilist probing
