irqchip/renesas-rzg2l: Add macro to retrieve TITSR register offset based on register's index

Browse source

[ Upstream commit 2eca4731cc ]

There are 2 TITSR registers available on the IA55 interrupt controller.

Add a macro that retrieves the TITSR register offset based on it's
index. This macro is useful in when adding suspend/resume support so both
TITSR registers can be accessed in a for loop.
