i2c: at91: fix clk_offset for sama5d2
[ Upstream commit b1ac6704493fa14b5dc19eb6b69a73932361a131 ]
In SAMA5D2 datasheet, TWIHS_CWGR register rescription mentions clock
offset of 3 cycles (compared to 4 in eg. SAMA5D3).
Cc: stable@vger.kernel.org # 5.2.x
[needs applying to i2c-at91.c instead for earlier kernels]
Fixes: 0ef6f3213dac ("i2c: at91: add support for new alternative command mode")
