Philipp Zabel 1e703d621b Input: edt-ft5x06 - work around first register access error
[ Upstream commit e112324cc0 ]

The EP0700MLP1 returns bogus data on the first register read access
(reading the threshold parameter from register 0x00):

    edt_ft5x06 2-0038: crc error: 0xfc expected, got 0x40

It ignores writes until then. This patch adds a dummy read after which
the number of sensors and parameter read/writes work correctly.
