The recent commit "ARM: EXYNOS: add support for EXYNOS5440 SoC" broke
support for exynos5250 because of_machine_is_compatible() was used too
early in the boot process.  It also probably meant that the exynos5440
failed to use the proper iotable.  Switch to use
of_flat_dt_is_compatible() in both of these cases.

The failure I was seeing in exynos5250 because of this was:

Now that the additional enable bits in the enet PLL are handled
as gates, the gate_mask is identical for all plls. Remove the
gate_mask from the code and use the BM_PLL_ENABLE bit for
enabling/disabling the PLL.

In current code the ethernet PLL is not handled correctly. The PLL runs at 500MHz
and has different outputs. Only the enet reference clock is implemented. This
patch changes the PLL so that it outputs 500MHz and adds the additional outputs
as dividers. This now matches the datasheet which says:

> This PLL synthesizes a low jitter clock from 24 MHz reference clock.
> The PLL outputs a 500 MHz clock. The reference clocks generated by this PLL are:
>  • Ref_PCIe = 125 MHz
>  • Ref_SATA = 100 MHz
>  • Ref_ethernet, which is configurable based on the PLL_ENET[1:0] register field.

Add a new pinctrl driver for Samsung EXYNOS5440 SoC. The pin controller
module in EXYNOS5440 is different from the pin controller found on other
Samsung SoC. Hence, the pin controller driver for EXYNOS5440 SoC is
independent of the Samsung pinctrl framework.

From Alexander Shiyan:

The main direction of this patchset - approaching the platform to the
possibility of using configurations with multiple platforms in a single
kernel. Added support of the majority of the necessary kernel symbol.
Also part of the driver code used only for the platform was moved to the
board code and converted to the use of standard drivers.
