[PATCH v4 1/9] media: hantro: use G1_REG_INTERRUPT directly for the mpeg2

From: Emil Velikov <emil.velikov at collabora.com>

Use the register directly over the existing SWREG().

Ideally we'll port the driver away from the local registers, but for
now this is enough. For context - I was reading through the IRQ register
handling across the variants.
