soc/tegra: pmc: Fix uninitialised clock rate
For legacy 32-bit Tegra devices, the warning in the
tegra_pmc_enter_suspend_mode() function is being triggered because the
early_pmc->rate variable is never configured and hence, always 0. This
issue started occurring after updating the PMC driver to create the PMC
context dynamically which causes the 'rate' to be set in the new dynamic
context, but missed updating the rate in the early PMC context.
Fix this by initialising the early_pmc->rate variable for 32-bit Tegra
devices when the rate for the PMC context is initialised.
