clk: zynqmp: pll: add set_pll_mode to check condition in zynqmp_pll_enable
If there is a IOCTL_SET_PLL_FRAC_MODE request sent to ATF ever,
we shouldn't skip invoking PM_CLOCK_ENABLE fn even though this
pll has been enabled. In ATF implementation, it will only assign
the mode to the variable (struct pm_pll *)pll->mode when handling
IOCTL_SET_PLL_FRAC_MODE call. Invoking PM_CLOCK_ENABLE can force
ATF send request to PWU to set the pll mode to PLL's register.
There is a scenario that happens in enabling VPLL_INT(clk_id:96):
1) VPLL_INT has been enabled during booting.
2) A driver calls clk_set_rate and according to the rate, the VPLL_INT
should be set to FRAC mode. Then zynqmp_pll_set_mode is called
to pass IOCTL_SET_PLL_FRAC_MODE to ATF. Note that at this point
ATF just stores the mode to a variable.
3) This driver calls clk_prepare_enable and zynqmp_pll_enable is
called to try to enable VPLL_INT pll. Because of 1), the function
zynqmp_pll_enable just returns without doing anything after checking
that this pll has been enabled.
In the scenario above, the pll mode of VPLL_INT will never be set
successfully. So adding set_pll_mode to check condition to fix it.

reporting warnings. I thought I fixed those! Looking closer at the
fix, I see that I totally bungled it (or at least I halfway bungled
it). The SD card clock got fixed (and that was the one I was really
focused on fixing), but I totally adjusted the wrong clock for eMMC.
Sigh. Let's fix my dumb mistake.
Now both SD and eMMC have floor for the "apps" clock.
This doesn't matter a lot for the final clock rate for HS400 eMMC but
could matter if someone happens to put some slower eMMC on a sc7180.
We also transition through some of these lower rates sometimes and
having them wrong could cause problems during these transitions.
