clk: qcom: gcc-sdm660: Replace usage of parent_names

Using parent_data and parent_hws, instead of parent_names, does protect
against some cases of incompletely defined clock trees. While it turns
out that the bug being chased this time was totally unrelated, this
patch converts the SDM660 GCC driver to avoid such issues.

The "xo" fixed_factor clock is unused within the gcc driver, but
referenced from the DSI PHY. So it's left in place until the DSI driver
is updated.

clk: qcom: a53pll/mux: Use unique clock name

Different from MSM8916 which has only one a53pll/mux clock, MSM8939 gets
three for Cluster0 (little cores), Cluster1 (big cores) and CCI (Cache
Coherent Interconnect).  That said, a53pll/mux clock needs to be named
uniquely.  Append @unit-address of device node to the clock name, so
that a53pll/mux will be named like below on MSM8939.

  a53pll@b016000
  a53pll@b116000
  a53pll@b1d0000

  a53mux@b1d1000
  a53mux@b011000
  a53mux@b111000

clk: qcom: apcs-msm8916: Flag a53mux instead of a53pll as critical

The clock source for MSM8916 cpu cores is like below.

                        |\
         a53pll --------| \ a53mux     +------+
                        | |------------| cpus |
     gpll0_vote --------| /            +------+
                        |/

So a53mux rather than a53pll is actually the parent clock of cpu cores.
It makes more sense to flag a53mux as critical instead, so that when
either a53pll or gpll0_vote is used by cpu cores, the clock will be kept
enabled while the other can be disabled.

clk: divider: Implement and wire up .determine_rate by default

.determine_rate is meant to replace .round_rate. The former comes with a
benefit which is especially relevant on 32-bit systems: since
.determine_rate uses an "unsigned long" (compared to a "signed long"
which is used by .round_rate) the maximum value on 32-bit systems
increases from 2^31 (or approx. 2.14GHz) to 2^32 (or approx. 4.29GHz).

Implement .determine_rate in addition to .round_rate so drivers that are
using clk_divider_{ro_,}ops can benefit from this by default. Keep the
.round_rate callback for now since some drivers rely on
clk_divider_ops.round_rate being implemented.

clk: mediatek: Add configurable enable control to mtk_pll_data

In all MediaTek PLL design, bit0 of CON0 register is always
the enable bit.
However, there's a special case of usbpll on MT8192.
The enable bit of usbpll is moved to bit2 of other register.
Add configurable en_reg and pll_en_bit for enable control or
default 0 where pll data are static variables.
Hence, CON0_BASE_EN could also be removed.
And there might have another special case on other chips,
the enable bit is still on CON0 register but not at bit0.

clk: mediatek: Fix asymmetrical PLL enable and disable control

In fact, the en_mask is a combination of divider enable mask
and pll enable bit(bit0).
Before this patch, we enabled both divider mask and bit0 in prepare(),
but only cleared the bit0 in unprepare().
In the future, we hope en_mask will only be used as divider enable mask.
The enable register(CON0) will be set in 2 steps:
first is divider mask, and then bit0 during prepare(), and vice versa.
But considering backward compatibility, at this stage we allow en_mask
to be a combination or a pure divider enable mask.
And then we will make en_mask a pure divider enable mask in another
following patch series.
