[PATCH 2/3] media: atomisp: Use the actual value of the enum instead of the enum

[Ricardo Ribalda <ribalda@chromium.org>]

hrt_isp_css_irq_sw_pin_0 has a different enum type than
irq_sw_channel_id_t.

Replace it with the actual value of hrt_isp_css_irq_sw_pin_0 to avoid
arithmetic operations between different enum types (and make the
compiler happy).

It is required to build with llvm 9 without these warnings:
drivers/staging/media/atomisp/pci/sh_css_hrt.c:68:19: warning: arithmetic between different enumeration types ('irq_sw_channel_id_t' and 'enum hrt_isp_css_irq') [-Wenum-enum-conversion]

drivers/staging/media/atomisp/pci/sh_css.c:1237:40: warning: arithmetic between different enumeration types ('irq_sw_channel_id_t' and 'enum hrt_isp_css_irq') [-Wenum-enum-conversion]
