slave's supported single/dual/quad mode settings.

I'm doing some SPI work so I tried to compile all the drivers on my
sunxi board to try and avoid some regressions. This failed, so here are
some fixes for this.

Upstream kernel linux use a different compatible mediatek,spi-ipm.

Add support for this compatible and add handling for the additional
clock similar to how it's done by the upstream driver and handling for
all the property enabled by default.

With commit 793e62301180 ("spi: mtk_spim: get spi clk rate only once") a
new system to calculate the SPI clocks has been added.

Unfortunately, the do_div macro overrides the global priv->pll_clk_rate
field. This will cause to have a reduced clock rate on each subsequent
SPI call.

In u-boot we don't use IRQ. Instead, we poll busy bit in SPI_STATUS.

However these IRQ enable bits may be set in previous boot stage (BootROM).

If we leave these bits not cleared, although u-boot has disabled IRQ and
nothing will happen, the linux kernel may encounter panic during
initializing the spim driver due to IRQ event happens before IRQ handler
is properly setup.

This patch clear IRQ bits to prevent this from happening.

We don't really need to switch clk rate during operating SPIM controller.
Get clk rate only once at driver probing.

The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU
can expect 64-bit data from the device tree parser, so use
devfdt_get_addr_ptr instead of the devfdt_get_addr function in
the various files in the drivers directory that cast to a pointer.
