Version bumped to 0.4.904 (Version 0.5 RC5)
This fifth release candidate had lots of changes made to the analog
VGA output control portion of the code. I sure hope there are no
regressions.

Using SR01[5] to turn off analog VGA output rather than CR47[2]
CR47[2] (3X5.47[2]) is the âback doorâ register to turn off analog
VGA output. Will rather use the âfront doorâ version of it located
at SR01[5] (3C5.01[5]).

Added viaAnalogInit
This function initializes several analog VGA output DAC related
registers. It is called from via_analog_mode_set callback function
during mode setting for analog VGA output.

Small fix to VT1632(A) detection
via_vt1632_detect was checking the 0x02 flag by using the boolean
and operator instead of the binary one, which causes any non-zero
value to set the status as connected.

Not turning on analog VGA output DAC within via_analog_mode_set
Analog VGA output DAC should be turned on only by via_analog_dpms
callback function, and via_analog_mode_set callback function
should not be touching it.

Turning off analog VGA output DAC rather than IGA1 DPMS state
Previously, in order to turn off analog VGA output, the code was
putting IGA1 to DPMS off state. The correct way to turn off analog
VGA output is to control its DAC output state.

Some of the register bits of CR47 (3X5.47) should be initialized
within viaIGAInitCommon function rather than viaIGA1Init function
since viaIGA1Init function will not be called if only IGA2 is used.
