[PATCH 4/7] spi: cadance: Fix the Documentation

[Shubhrajyoti Datta <shubhrajyoti.datta-gjFFaj9aHVfQT0dZR+AlfA@public.gmane.org>]

cdns_spi_chipselect has parameter is_high however the comment
describes it as is_on.
Also fixes the below warning.
drivers/spi/spi-cadence.c:182: warning: No description found for
parameter 'is_high'
drivers/spi/spi-cadence.c:182: warning: Excess function parameter 'is_on'
description in 'cdns_spi_chipselect'
