drm/nouveau/disp: Fix missing backlight control on Macbook 5,1
Macbook 5,1 with MCP79 lost its backlight control since the recent change for supporting GSP-RM; it rewrote the whole nv50 backlight control code and each display engine is supposed to have an entry for IOR bl callback, but it didn't cover mcp77. This patch adds the missing bl entry initialization for mcp77 display engine to recover the backlight control.
