[PATCH v6] staging: sm750fb: Remove unused variable 'setAllEngOff'

["André Moreira" <andrem.33333@gmail.com>]

The variable 'setAllEngOff' within the 'init_status' struct is only
set to zero during setup but its value is never read anywhere else
in the driver. Remove it entirely to clean up the code.

v6:
  - Change patch approach from renaming CamelCase to entirely removing
    the unused 'setAllEngOff' variable, based on Greg KH's feedback.

v5:
  - Fix broken diff from v4 that was accidentally recreating the entire struct.
  - Update the variable usage inside drivers/staging/sm750fb/sm750.c to
    prevent compilation errors.

v4:
  - Drop register renames 'pvReg' to 'regs' as they were merged via another upstream patch.
  - Keep only the 'init_status' CamelCase cleanup.

v3:
  - Added changelog history to satisfy the bot.

v2:
  - Renamed 'pv_reg' to 'regs' to completely remove Hungarian notation, based on Greg KH's feedback.
