Lucas Tanure 344a55ccf5 i2c: cadence: Increase timeout per message if necessary
[ Upstream commit 96789dce04 ]

Timeout as 1 second sets an upper limit on the length
of the transfer executed, but there is no maximum length
of a write or read message set in i2c_adapter_quirks for
this controller.

This upper limit affects devices that require sending
large firmware blobs over I2C.

To remove that limitation, calculate the minimal time
necessary, plus some wiggle room, for every message and
use it instead of the default one second, if more than
one second.
