clk: qcom: smd-rpm: Add .recalc_rate hook for clk_smd_rpm_branch_ops

As there is a `rate` field in clk_smd_rpm, clk_smd_rpm_recalc_rate() can
be used by branch clocks to report rate as well, rather than assuming
the rate is always same as parent clock.  This assumption doesn't hold
on platforms like QCM2290, where xo_board is 38.4MHz while bi_tcxo is
19.2MHz.

To get this work, XO buffered clocks need the following updates.

- Assign a correct rate rather than the fake one which is being used to
  generate binary value for clk_smd_rpm_req interface.

- Explicitly handle the clk_smd_rpm_req interface value for XO buffered
  clocks (.rpm_res_type being QCOM_SMD_RPM_CLK_BUF_A).
