arm64: dts: ti: k3-j722s: Add main_i2c4 device node

Browse source

Add missing device tree node for main_i2c4, and the corresponding ranges
in cbass_main. Interrupt for this i2c controller is routed through the
Main GPIOMUX Router.
Base address, Interrupt IDs are taken from J722S TRM [0].
Device, Clock IDs are taken from TISCI docs [1].

Additionally, the I2C4 is the only interrupt source to the GPIOMUX INTR
router that generates level interrupts, while all other sources generate
edge interrupts. Due to this, the router needs to handle interrupt-type
on a per-line basis. Modify the router node and its consumers to
specify the interrupt type corresponding to each interrupt line.
