[PATCH v2 2/2] spi: sh-hspi: Do not specifically request shyway_clk clock

[Simon Horman <horms+renesas@verge.net.au>]

Rather than requesting the shyway_clk call clk_get with
the device and a NULL con_id.

This is in keeping with the way that clk_get() is called
on other drivers used by Renesas Gen 1 SoCs. And I believe
it is compatible with supplying clocks via DT, unlike the current code.

It appears to me that the two uses of this driver are
the r8a7778 and r8a7779 SoCs.

The r8a7779 already clocks setup to allow this driver to continue to work
with this change applied.

The r8a7778 has clocks incorrectly setup to allow this driver to continue
to work with this change applied. This problem is addressed in
"ARM: shmobile: r8a7779: Use clks as MSTP007 parent" which is thus
a pre-requisite of this patch.
