[PATCH AUTOSEL 5.15 02/10] irqchip/ocelot: Fix trigger register address

[Sasha Levin]

From: Sergey Matsievskiy <matsievskiysv@xxxxxxxxx>

[ Upstream commit 9e9c4666abb5bb444dac37e2d7eb5250c8d52a45 ]

Controllers, supported by this driver, have two sets of registers:

 * (main) interrupt registers control peripheral interrupt sources.

 * device interrupt registers configure per-device (network interface)
   interrupts and act as an extra stage before the main interrupt
   registers.

In the driver unmask code, device trigger registers are used in the mask
calculation of the main interrupt sticky register, mixing two kinds of
registers.

Use the main interrupt trigger register instead.
