MLK-17626: drm: imx: dcss: fix "ctxld error" messages
The problem arised because of a combination of 2 commits:
Commit 1:
"2a70f32 - MLK-17232-2: drm: imx: dcss: ignore SB_PEND_DISP_ACTIVE
interrupt"
disabled the SB_PEND_DISP_ACTIVE interrupt because of a problem in SOC.
However, it did not remove the flag from CTXLD_IRQ_ERROR macro.
Commit 2:
"f0e3911 - MLK-17459-1: drm: imx: dcss: change ctxld irq handling"
moved the bottom half interrupt handling to top half. By doing that, the
top half did not exit immediately if IRQ_COMPLETION condition was met
and continued evaluating if any interrupts in CTXLD_IRQ_ERROR flags
were triggered.
This patch removes SB_PEND_DISP_ACTIVE interrupt flag from
CTXLD_IRQ_ERROR macro.
