[Qemu-trivial] [PATCH v2 02/14] sm501: Use defines instead of constants where available

[BALATON Zoltan]

This also fixes the initial value of misc_control register to match the
comment which is likely what was intended but the DAC_POWER bit was set
instead. This value is unused so it does not really matter but is
fixed here for consistency.
