ARM: at91/avr32/atmel_lcdfb: add bus-clock entry

Add hclk entry for the atmel_lcdfb bus clock.

On at91sam9261, at91sam9g10 and at32ap the bus clock has to be enabled
as well as the peripheral clock. Add the appropriate lookup entries to
these SOCs and fake clocks to the SOCs that do not use it.

This allows us to get rid of the conditional enabling of the clocks in
the driver which relied on the cpu_is macros.

Tested on at91sam9263 and at91sam9g45, compile-tested for other
AT91-SOCs, and untested for AVR32.

atmel_lcdfb: move lcdcon2 register access to compute_hozval

Pass atmel_lcd_info structure to compute_hozval and only do the register
access on SOCs that actually use it.

This will also simplify the removal of the cpu_is macros.

ARM: at91/avr32/atmel_lcdfb: add platform device-id table

Add platform device-id table in order to identify the controller and
determine its configuration.

The currently used configuration parameters are:

have_alt_pixclock
 - SOC uses an alternate pixel-clock calculation formula (at91sam9g45
   non-ES)

have_hozval
 - SOC has a HOZVAL field in LCDFRMCFG which is used to determine the
   linesize for STN displays (at91sam9261, at921sam9g10 and at32ap)

have_intensity_bit
 - SOC uses IBGR:555 rather than BGR:565 16-bit pixel layout
   (at91sam9261, at91sam9263 and at91sam9rl)

This allows us to remove all the remaining uses of cpu_is macros from
the driver.

Tested on at91sam9263 and at91sam9g45, compile-tested for other
AT91-SOCs, and untested for AVR32.
