media: camss: csid-170: don't enable unused irqs

[ Upstream commit a6da362491e409de0978d733441e59db6584d69f ]

csid_isr() only checks for the reset irq, so enabling any other irqs
doesn't make sense. The "RDI irq" comment is also wrong, the register
should be CSID_CSI2_RDIN_IRQ_MASK. Without this fix there may be an
excessive amount of irqs.
