Subject: [PATCH 05/22 v4] Input: atmel_mxt_ts - don't read T5 when dumping objects

T5 is the message processor object.  Reading it will only have two
outcomes, neither of which is particularly useful:
 1) the message count decrements, and a valid message will be lost
 2) an invalid message will be read (reportid == 0xff)
