Kconfig: reduce the amount of power sequencing noise

Browse Source 
Kconfig will ask the user twice about power sequencing: once for the QCom
WCN power sequencing driver and then again for the PCI power control
driver using it.

Let's automate the selection of PCI_PWRCTL by introducing a new hidden
symbol: HAVE_PWRCTL which should be selected by all platforms that have
the need to include PCI power control code (right now: only ARCH_QCOM).

The pwrseq-based PCI pwrctl driver itself will then be selected by the
drivers binding to devices that may require external handling of the
power-up sequence (currently: ath11k and ath12k) based on the value
of HAVE_PWRCTL.

Make all PCI pwrctl Kconfig symbols hidden so that no questions are
asked during configuration.
