Remove notes about migrating from the old driver which is
retired as all users are now migrated.
Update the text to reflect that we support PL110 and PL111
alike.
Drop the bullet on memory bandwidth scaling: this has been
implemented.

and it took a little more than 3 years to do this
properly without leaving any platforms behind.

As the framebuffer subsystem is orphaned I expect this to
go in through the drm-misc tree.

The PL111 DRM driver is now the sole user of the external
CLCD registers header file, so let's absorb that into the
pl111_drm.h file and save the external include.

This moves over some of the credit for the development of this
driver from the old fbdev driver that I used as reference when
getting this in place.

Further I wrote:
You should definately insert code to read the MTP bytes:
0xDA manufacturer
0xDB driver version
0xDC LCD module/driver
And print these, se e.g. my newly added NT35510 driver or
the Sony ACX424AKP driver.
So please do that.

Linus Walleij
