drivers/intel/mipi_camera: Remove IPU ES support entry for ADL-N
The current IPU ES entry value is always set to true for ADL-N and
kernel picks the ES version of the main IPU FW even for the production
bootloader but loading is not successful due to the authentication
failure.
Alderlake-N silicon has the same CPU id for all the SKU's and
also the production binaries are backward compatible with ES parts.
This change removes the IPU ES support ACPI entry since the
kernel needs to load the production IPU main firmware on both the
ES/QS parts.
BUG=b:248249032
TEST=Verify the Camera functionality by enabling the IPU secure mode
on ADL-N variants with both ES/QS silicon.
