Subject: [PATCH v3 3/4] i2c: at91: remote default value initialization

From: Eugen Hristev <eugen.hristev@...rochip.com>

Platform data structs are initialized by default with zero values.
Thus it becomes redundant to initialize them manually to zero (false).
Remove extra false initialization for field members in structs.
