[PATCH 00/11] Intel pmc_core: Enable telemetry

On Intel SoCs, registers for the Power Management Controller are available
in the PCI BAR of the SSRAM device, 0000:14.2. On Meteor Lake, these
registers are structured in Intel PMT Telemetry regions which could be
handled by the pmt_telemetry driver. This series adds APIs to the
intel_vsec and pmt_telemetry drivers so that pmc_core driver can both
create the telemetry instance from the SSRAM device and register for a
handle to read the telemetry which contains the low power mode requirements
for the S0ix states supported by Meteor Lake. The series also adds some
fixes.
