mmc: meson-gx: improve meson_mmc_clk_set
The following changes are quite small, therefore I combined them in
one patch.
- ret doesn't need to be initialized with 0
- use standard !clk_rate notation to check for a zero value
- If clk_rate is zero we return here. Therefore all further checks
in this function for clk_rate != 0 are not needed.
- switch from dev_warn to dev_err if the clock can't be set
- If due to clock source and available divider values the requested
frequency isn't matched exactly (always the case if requested
frequency is 52 MHz), then just print the differing values as
debug message and not as warning.
- Also remove ret from the message as it is always 0.
- Set member current_clock to the current requested rate and
mmc->actual_clock to the current actual rate
