288e088f8a atirage: Fix hardware cursor update.
Switching from Watch to Arrow cursor at vertical position zero (top of the screen) would sometimes cut off the top half of the Arrow cursor. The following changes fix this:

Use the new cursor_dirty flag to signal when the cursor should be updated. This reduces the number of cursor updates and doesn't depend on registers being accessed in a specific order.

Set the cursor_dirty flag for any change that should cause the hardware cursor to be updated:
- CUR_CLR0, CUR_CLR1: Cursor color changes. We don't check if the colors actually changed (all cursors are usually black and white). Rather, writes to these registers usually means the cursor bytes have changed or will change.
- CUR_OFFSET: Offset to cursor bytes.
- CUR_VERT_OFF: First vertical line of cursor to draw.
Other changes that don't require the cursor to be updated:
- CUR_HORZ_OFF: Horizontal offset of cursor position. The cursor is unchanged - just need to adjust the drawing position.
- CUR_HORZ_VERT_POSN: The cursor is unchanged - only the drawing position is changed.
The only thing that could change the cursor that we don't check is a change to the cursor bytes.

e14b6677b2 displayid: Fix non-extended sense codes.
Sense codes for displays like the 12 inch RGB display (512x384) weren't working since they had the extended part set to 0xff.
Related to issues #25.
Also added some descriptive information and sizes which may be used for UI purposes such as creating a menu of displays to choose from. The sizes may be used to set the default window size for the display.

288d97f24c atimach64gx: Add missing WRITE_VALUE_AND_LOG.
This commit fixes conflict resolution mistakes in the following commits:
"atimach64gx: Let crtc_update calculate fb_ptr."
"atimach64gx: Redraw only when necessary."

"atimach64gx: Log unhandled overlay registers." was mistakenly included in "atimach64gx: Let crtc_update calculate fb_ptr.". The OVR_ registers were included because they may be needed for 2D acceleration in System 7.5.3 and later.

2c79171be6 atimach64gx: Fix CONFIG_CNTL and MM_REGS_OFFSET.
Init them to defaults.
Make CONFIG_CNTL 8 bytes so unaligned read/write is easier.
Write changes to CONFIG_CNTL even if offset + size is > 4.
Log aperture change only if first byte (LSB) of CONFIG_CNTL is written. The driver might only write to the 2 most significant bytes which won't affect aperture size.
Offset and size are applied to the destination, not to source value, so we shouldn't use extract_bits when logging value.
Use ATI bitfield enums in switch statement.

d06d80619e viacuda: Add 1 Sec Timer, fix Get/Set Real Time.
GET_REAL_TIME was using the wrong offset and wasn't setting out_count.

May need to add time zone offset which could be different between host and guest.
get-time and set-time can be tested in Open Firmware.
SET_REAL_TIME is used by the Date/Time Control Panel when you change the date.
It is unknown what method Mac OS uses to get the time at boot. Mac OS 8.6 does not use GET_REAL_TIME during boot, so the time is left as 12:00 AM Jan 1, 1904.
