[PATCH v2 2/5] drivers: acpi: acpi_apd: Remove unused device property "is-rv"

[PATCH v2 2/5] drivers: acpi: acpi_apd: Remove unused device property "is-rv"

[Ajit Kumar Pandey]

Initially "is-rv" device property is added for 48MHz fixed clock
support on Raven or RV architecture. It's unused now as we moved
to clock config based selection to extend such support on others
architecture. This change removed unused code from acpi driver.
