[U-Boot] [PATCH 01/03 v2] Add inverted clock polarity support for Atmel LCD driver

[Dimitar Dimitrov <dinuxbg@gmail.com>]

This is my second try for Olimex SAM9-L9260/61 board support patches. 
I deleted the board ethernet initialization and hopefully will add
it later in a state that can be accepted.

Here follows the first patch.

Boards utilizing the Atmel LCD driver can now specify that the LCD clock must
be inverted by defining the macro CONFIG_ATMEL_LCD_INVCLK.
