AUDIO_AXI_CLK_ROOT, not AUDIO_AHB_CLK_ROOT. Update the clock data

After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all clk drivers to use .remove(), with the eventual goal to drop
struct platform_driver::remove_new(). As .remove() and .remove_new() have
the same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

According to Reference Manual of i.MX8MP
The parent clock of "earc_phy" is "sai_pll_out_div2",
The parent clock of "audpll" is "osc_24m".
Add CLK_GATE_PARENT() macro for usage of specifying parent clock.

Audiomix block control can be a reset controller for
Enhanced Audio Return Channel (EARC), which is one of

The reset controller is supported by the auxiliary device

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Replace SET_RUNTIME_PM_OPS() with its modern alternative RUNTIME_PM_OPS().
The combined usage of pm_ptr() and RUNTIME_PM_OPS() allows the
compiler to evaluate if the suspend/resume() functions are used at
buid time or are simply dead code.
This fixes the following s390 allmodconfig build errors:

Unlike the other block control IPs in i.MX8M, the audiomix is mostly a
series of clock gates and muxes. Model it as a large static table of
gates and muxes with one exception, which is the PLL14xx . The PLL14xx
SAI PLL has to be registered separately.
