redhat/configs: aarch64: compile cpufreq-dt-platdev as built-in

JIRA: https://issues.redhat.com/browse/RHEL-68851
Upstream-status: RHEL-only

This driver provides the virtual cpufreq-dt device on platforms that
support generic Device Tree based cpufreq control. It can be built as a
module since upstream commit 3b062a0 ("cpufreq: dt-platdev: Support
building as module"), but unfortunately this causes a regression on some
platforms because the module does not autoload. This further prevents
the cpufreq-dt driver from probing, leaving the platform with no cpufreq
support. An example of such platform is the Renesas R-Car S4 board.

Change the configuration to compile the cpufreq-dt-platdev as built-in.
This future proofs the configuration, since this was reported [1] and
fixed [2] upstream by confining the cpufreq-dt-platdev driver to be
built-in. It also aligns the configuration with ARK and CS10, at least
for automotive (the driver is disabled altogether for the rest of RHEL).
