Raymond Lei 581e7ff2aa drivers: spi: nxp: flexiospi spi_loopback test failed on flexio spi
Several reason cause loopback test failed:
a) FlexIO input frequency is not correct, on RT11xx, input freq is 24M,
while max baud rate can reach 1/4 of input freq, so it can only support
6Mbps.
b) Flexio shift register depend on correct timer output to triggger TX
and RX, if timer comparison value is not accurate, RX error happens on
high baud rate. This is the reason why test fails on RT1060.

also fix a error on FlexIO clock ID calculation.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
