i2c: at91: fix clk_offset for sama5d2
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") Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Acked-by: Ludovic Desroches <ludovic.desroches@microchip.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
