The desired_perf is an abstract performance number. Its value should
be in the range of [lowest perf, highest perf] of CPPC.

Based on 8.4.7.1 section of ACPI 6.1 specification, if the platform
supports CPPC, the _CPC object must exist under all processor objects.
If cpc_desc_ptr pointer is invalid on any CPUs, acpi_get_psd_map()
should return error and CPPC cpufreq driver can not be registered.

Based on 8.4.7.1 section of ACPI 6.1 specification, if the platform
supports CPPC, the _CPC object must exist under all processor objects.
If cpc_desc_ptr pointer is invalid on any CPUs, acpi_get_psd_map()
should return error and CPPC cpufreq driver can not be registered.

This patch adds fractional scale clock support.
Fractional scale clock is implemented for a single register field.
Output rate = parent_rate * scale / denominator
For example, for 1 / 8 fractional scale, denominator will be 8 and scale
will be computed and programmed accordingly.

This change adds request mailbox channel by index. It allows the mailbox
client to request a channel without create a DT node.
