Subject: [PATCH v4 4/8] irqchip: rtd1195-mux: Add RTD1195 definitions

Add compatible strings and bit mappings for Realtek RTD1195 SoC.

Signed-off-by: Andreas Färber <[email protected]>
---
v3 -> v4:
* Use tabular formatting (Thomas)
* Adopt different braces style (Thomas)
* Updated with shortened isr_to_int_en_mask callback name (Thomas)
* Renamed functions and variables from rtd119x_ to rtd1195_
* Renamed enum values from RTD119X_ to RTD1195_

v3: New
