Added flt state machine thread to ensure that frl cts can pass:
1.Support txFFE Level switch.
2.Support LTS4.
3.Polling sink frl status after flt pass.

This adds a standalone driver to support PCIe hotplug functionality
merely based on a GPIO indicating the status of a downstream device
connectivity. It looks for "hotplug-gpios" property in the corresponding
device node to get the GPIO information.
It also provides a mechanism for platform drivers of the controllers
to register ops to perform any platform specific operations while
enabling/disabling the slots.

When switching sample rates, the clock settings are as follows:
- For 48K, MCLK = 256fs = 256 * 48K = 12288K
- For 16K, MCLK = 256fs = 256 * 16K = 4096K
- For 8K, MCLK = 256fs = 256 * 8K = 2048K
The `set_sysclk` function in the soc i2s_tdm controller does not
actually perform `clk_set_rate`; it merely passes the parameters.
The actual `clk_set_rate` is called during `i2s_tdm_hw_params`.
However, `rk817_hw_params` performs `restart_clk_apll` inside,
which sets the PLL parameters that do not match the MCLK,
resulting in silence. To resolve this, clk_set_rate for the MCLK
frequency should be called within the set_sysclk function.

According to SPI signal test results:
(1) When using SPI IOs under 3.3V power domain, need to increase
driver strength to level3.
(2) When using SPI IOs under 1.8V power domain, use default driver
strength(level2) is best.

In some manufacturers, we have found that the i2c clk/data
pullup power is disabled when the system is shutdown or suspended,
As a result, the first i2c communication fails when probing
or resuming. Therefore, it is necessary to perform i2c
communication once by default when probing or resuming.
