Input: ads7846 - ratelimit the spi_sync error message

[ Upstream commit ccbfea78adf75d3d9e87aa739dab83254f5333fa ]

In case the touch controller is not connected, this message keeps scrolling
on the console indefinitelly. Ratelimit it to avoid filling kernel logs.

ads7846 spi2.1: spi_sync --> -22
