Add a level 2 interrupt controller for the RV32M1 SoC. This uses the INTMUX peripheral. As a first customer, convert the timer driver over to using this, adding nodes for the LPTMR peripherals. This lets users select the timer instance they want to use, and what intmux channel they want to route its interrupt to, using DT overlays.

Select this option to enable support for the RV32M1 INTMUX

driver. This provides a level 2 interrupt controller for the SoC.
|

The INTMUX peripheral combines level 2 interrupts into
|

eight channels; each channel has its own level 1 interrupt to

the core.
