10d5d99e88 [ARM] pxa/hx4700: fix hx4700 touchscreen pressure values 
hx4700 touchscreen events were being dropped in ads7846_rx() because their
pressure values consistently exceeded the platform maximum of 512; a sample
of 256 pressure values were in the range 531 to 815.  Doubling the platform
maximum to 1024 allows hx4700 touchscreen events to pass the test.

e2c509c7e6 [ARM] pxa/hx4700: use platform_lcd driver 
Instead of directly registering an lcd_device, use the platform_lcd driver.
This fixes a broken build in case CONFIG_LCD_CLASS_DEVICE is not enabled.
