Subject: [PATCH 1/1] irqchip: Add config MTK_SYSIRQ and MTK_CIRQ

Mediatek sysirq and cirq drivers as-is were bound together to the config
of ARCH_MEDIATEK.  These two drivers should be able to be configured
separately.  For example, on new Mediatek mobile chips such as Dimensity
820, the sysirq driver is not used since the hardware module is removed.

Add two new configs to sysirq and cirq drivers.
- config MTK_SYSIRQ for the interrupt polarity controller driver: sysirq
- config MTK_CIRQ for the low-power interrupt driver: cirq
