i2c: bcm2835: Avoid clock stretching timeouts
[ Upstream commit 9495b9b31abe525ebd93da58de2c88b9f66d3a0e ]
The CLKT register contains at poweron 0x40, which at our typical 100kHz
bus rate means .64ms. But there is no specified limit to how long devices
should be able to stretch the clocks, so just disable the timeout. We
still have a timeout wrapping the entire transfer.
