Subject: staging: sm750fb: Correctly set CLOCK_PHASE bit of display controller.

From: Phil Turnbull <[email protected]>

commit 992f961480d23e9ef9e686e512a419efef723523 upstream.

Commit 6fba39cf32a3 ("staging: sm750fb: use BIT macro for PANEL_DISPLAY_CTRL single-bit fields") accidentally changed the CLOCK_PHASE logic from '|=' to '=' which clears all the previously set bits.

Fixes 6fba39cf32a3 ("staging: sm750fb: use BIT macro for PANEL_DISPLAY_CTRL single-bit fields")
