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")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
