juno:Fix CSS_USE_SCMI_SDS_DRIVER=0 configuration

A previous commit 89f2e589856f ("plat/arm: remove weak implemention of
'plat_arm_psci_override_pm_ops' function") introduced a problem with the
CSS_USE_SCMI_SDS_DRIVER configuration. In juno_pm.c the
css_scmi_override_pm_ops function was used regardless of whether the
flag was set. This patch ifdefs the function to restore the original
behaviour.

zynqmp: pm: Reimplement clock set parent EEMI API

Clock set parent EEMI API is reimplemented to use system-level clock
and pll EEMI APIs rather than direct MMIO read/write accesses to clock
and pll control registers.
Since linux still uses clock set parent API to set pre_src, post_src, div2
and bypass, in the implementation of pm_clock_set_parent() we need to
workaround this by distinguishing two cases:
1) if the given clock ID corresponds to a PLL-related clock ID (*_PRE_SRC,
*_POST_SRC, *_INT_MUX or *PLL clock IDs); or 2) given clock ID is truly
an on-chip clock.
For case 1) we'll map the call onto PLL set parameter EEMI API with the
respective parameter ID. Since clock set parent interface to EL1/2 receives
parent index (mux select value), the value is just passed to PMU.
Functions that appear to be unused after this change is made are removed.

Setting the parent of *PLL clocks, that actually model bypass, is not
possible. This is already ensured by the existing clock model having the
CLK_SET_RATE_NO_REPARENT flag. The API also doesn't allow changing the
bypass parent. Bypass is controlled only by the PMU firmware.
