pmdomain: ti: Select PM_GENERIC_DOMAINS

[ Upstream commit fcddcb7e ]

Select PM_GENERIC_DOMAINS instead of depending on it to ensure
it is always enabled when TI_SCI_PM_DOMAINS is selected.
Since PM_GENERIC_DOMAINS is an implicit symbol, it can only be enabled
through 'select' and cannot be explicitly enabled in configuration.
This simplifies the dependency chain and prevents build issues
