Subject: fbdev: omap: pass irqs as resource
Git-commit: 81ad0f5bc476505781b1398be52a81eda3ee9798
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

To avoid relying on the mach/irqs.h header, stop using
OMAP_LCDC_IRQ and INT_1610_SoSSI_MATCH directly in the driver
code, but instead pass these as resources.
