Sunny Luo aa70617c04 spisg: fix mutex lock panic of dirspi_async [1/1] ...

PD#SWPL-179542

Problem:
dirspi_async is designed for the ldim isr. Unfortunately, the
clk_set_rate and clk_get_rate it calls use a mutex lock, which
will lead to a mutex lock panic.

Solution:
Set spi speed in spi_setup only when controller_data use_dirspi=1
Pre-save the spi speed to avoid calling clk_get_rate

Verify:
t5m
