d4044c2a6b e1000: use MII status register for link up/down 
Some guests will use the standard MII status register
to verify link state.  They will not notice link changes
unless this register is updated.

Verified with Linux 3.0 and Windows XP guests.

Without this patch, ethtool will report speed and duplex as
unknown when the link is down, but still report the link as
up.  This is because the Linux e1000 driver checks the
mac_reg[STATUS] register link state before it checks speed
and duplex, but uses the phy_reg[PHY_STATUS] register for
the actual link state check.  Fix by updating both registers
on link state changes.

Linux guest before:

242ea2c6bc versatilepb: Implement SYS_CLCD mux control register bits 
On the Versatile PB, PL110 graphics adaptor only natively supports
5551 pixel format; an external mux swaps bits around to allow
RGB565 and BGR565, under the control of bits [1:0] in the SYS_CLCD
system register.

Implement these SYS_CLCD register bits, and use a gpio line to
feed them out of the system register model, across the versatilepb
board and into the pl110 so we can select the right format.

This is necessary as recent Linux versatile kernels default to
programming the CLCD and mux for 16 bit BGR rather than 16 bit RGB.

Model the PL111 CLCD controller. This is a minor variation
on the PL110; the major programmer visible differences are
support for hardware cursor (unimplemented) and two new
pixel formats.

Since syborg_fb.c borrows the pl11x pixel drawing routines,
we also update it to cope with the new slightly larger array
of function pointers.
