i3c: dw-i3c-master: Add ACPI core clock frequency quirk

Some ACPI-enumerated devices like Tegra410 do not expose the controller
core clock through the clk framework. Unlike device tree, ACPI on Arm does
not model clock providers. The hardware is expected to have its clocks
enabled by firmware before the OS takes over.

Make the core clock optional and allow selected ACPI devices to provide the
core clock rate through the "clock-frequency" _DSD property when the core
clock is absent.

Resolve device quirks before acquiring the core clock so platforms without
the ACPI skip-clock quirk still fail probe immediately when the clock is
missing, before any MMIO access.
