ARM: at91: make at91sam926x_board_init board specific ...

The base addresses used in at91sam926x_board_init() differ with each
SoC. The board knows which SoC we are running on though, so create and
use SoC specific variants of these functions which pass the appropriate
base addresses to at91sam926x_board_init().

ARM: at91: drop at91_pmc_write()/at91_pmc_read() ...

at91_pmc_write() and at91_pmc_read() need a compile time base address,
so remove them.

ARM: at91rm9200ek: use plain readl/writel for pmc accesses ...

at91_pmc_write() needs a compile time base address, so rather use plain
read/writel.

ARM: at91sam926x use writel rather than pmc accessor function ...

The pmc accessor function depends on a compile time base address, so
rather use writel directly. In this case we can hardcode the base
address again since all at91sam926x SoCs have the same pmc base address.

ARM: at91: remove mach/io.h ...

Remove at91_sys_read() and at91_sys_write() since these are no longer
used. This makes mach/io.h empty so remove that aswell.

ARM: at91rm9200 timer: Make system timer defines SoC specific ...

- rename at91_st.h to at91rm9200_st.h
- rename prefix from AT91_ to AT91RM9200_
- remove register offset from System timer defines

ARM: at91rm9200 timer: remove unused include ...

at91rm9200_time.c doesn't need anything from at91_pmc.h, remove the
inclusion.

ARM: at91: remove common matrix header file ...

The common matrix header file can be removed when the users include the
SoC specific one. Fix the only user and remove the file.

ARM: at91: consolidate phy reset functions ...

Many boards have the same ethernet phy reset function, so share the code
in a common function.
While at it remove the AT91_RSTC offset from the rstc register defines.
AT91_RSTC was the offset between the AT91_SYSTEM_BASE and the reset
controller.

ARM: at91: remove AT91_SDRAM_BASE ...

AT91_SDRAM_BASE is only used in board code which known the SDRAM base
address, so we do not need a common define.

ARM: at91: drop AT91_NB_USART ...

AT91_NB_USART only used to return an error from at91_register_uart() if
an invalid UART number is passed. This will never happen as the linker
fails earlier in that case, so the runtime check can be removed and with
it the now unused AT91_NB_USART define.

ARM: at91: Add initial support for the EVB-KSZ9477 eval board ...

The EVB-KSZ9477 is an evaluation board for the KSZ9477 ethernet switch.
This board is equipped with a atsama5d3 SoC with 256MiB of SDRAM, 256MiB
of NAND flash and a SD card slot.

For now only second stage booting is supported with AT91bootstrap as
first stage loader.
