The correct pinctrl is handled automatically so we don't need to do it in
the driver. The exception is when we want to use a different chip select
(other than 0). But this isn't used at present.

At present there is an incorrect call to rkspi_enable_chip(). It should
be disabling the chip, not enabling it. Correct this and ensure that the
chip is disabled when releasing the bus.

Some devices need delays before and after activiation. Implement these
features in the SPI driver so that we will be able to enable the Chrome
OS EC.

Two of the init values are created locally so cannot be out of range.
The masking is unnecessary and in one case is incorrect. Fix it.

Rather than changing the clock to the same value on every transaction,
remember the last value and don't adjust the clock unless it is necessary.

If full pinctrl is enabled we don't need to manually set the pinctrl in the
driver. It will happen automatically. Adjust the code to suit - we will
still use manual mode in SPL.

We can use the new clk_get_by_index() function to get the correct clock.

We need to use %lx not %x to describe a fdt_addr_t

Add a SPI driver for the Rockchip RK3288, using driver model. It should work
for other Rockchip SoCs also.
