Similar to commit 3308a31c ("arm64: dts: ti: k3-am62: Add general
purpose timers for am62"), there are 12 general purpose timers on am62a7
split between 8 in main and 4 in mcu domains. The 4 in mcu domain do not
have interrupts that are routable to a53.

We configure the timers with the 25 MHz input clock by default as the
32.768 kHz clock may not be wired on the device. We leave the MCU domain
timers clock mux unconfigured, and mark the MCU domain timers reserved.
The MCU domain timers are likely reserved by the software for the ESM
module.
