[PATCH 4/5] spi: cadence-xspi: Don't use infinite timeout in register poll

[Paul Cercueil <paul.cercueil@bootlin.com>]

From: Tanmay Jagdale <tanmay@marvell.com>

The functions cdns_xspi_is_{sdma,stig}_ready() take a 'sleep' argument
which, if false, would result in the polling being a busy-wait.

But it would also switch to infinite timeouts, which we don't want.

Note that this code is dead right now ('sleep' is always true) but this
will change when panic write handling is implemented.
