iio: adc: at91_adc: Add support for touchscreens without TSMR
Old ADCs, as present on the sam9rl and the sam9g45 don't have a TSMR register
and the touchscreen support should be handled differently.

iio: adc: at91: cleanup platform_data
num_channels and registers are not used anymore since they are defined inside
the driver and assigned by matching the id_table.
Also, struct at91_adc_reg_desc is now only used inside the driver.

iio: at91: Use different prescal, startup mask in MR for different IP
For at91 boards, there are different IPs for adc. Different IPs has different
STARTUP & PRESCAL mask in ADC_MR.

ARM: AT91: Add platform data for the AT91 ADCs
The AT91 SoCs often embeds an ADC. This patch adds the needed
platform data to specify the informations required by the driver
to work properly.
For now, we only need the reference voltage and which channels
are available on the board.
