spi: mediatek: skip delays if they are 0
In the function 'mtk_spi_set_hw_cs_timing'
the 'setup', 'hold' and 'inactive' delays are configured.
In case those values are 0 it causes errors on mt8173:
cros-ec-i2c-tunnel 1100a000.spi:ec@0:i2c-tunnel0:
Error transferring EC i2c message -71
cros-ec-spi spi0.0: EC failed to respond in time.
This patch fixes that issues by setting only the values
that are not 0.
Fixes: 04e6bb0d6bb1 ("spi: modify set_cs_timing parameter")
