ARM: at91: replace at91sam9_ddrsdr.h with at91bootstrap's at91_ddrsdrc.h ...

Instead of adding missing definitions to the existing at91sam9_ddrsdr.h
and adapting the incoming DDRAM initialization code from at91bootstrap,
just replace the lightly used existing header with:
https://github.com/linux4sam/at91bootstrap/blob/v3.8.12/include/arch/at91_ddrsdrc.h

For easier comprehension, the replacement is done in three steps:
This last step copies the memory size querying functions from at91sam9_ddrsdr.h
to at91_ddrsdrc.h, then deletes it and fixes all references.

ARM: at91: fix at91sama5_get_ddram_size for sama5d4 ...

at91sama5_get_ddram_size() is despite the name specific to the
sama5d3 which it was added alongside of. sama5d4 board code continues
to use it, but accessing SAMA5D3_BASE_MPDDRC (0xffffea00) on
a sama5d4 should result in a Data Abort (Datasheet Figure 5-1)..

Fix this by giving at91sama5_get_ddram_size the mpddrc base
address as argument and migrate users to use one of two helpers
that specify the base address.

[afa: Sam didn't test this exact change, but tested the use
 of the critical part: accessing a different register]

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.

at91: serial: pullup RX pins, do not pullup TX pins ...

We have a number of sama5d3 devices that sometimes hangs at the
barebox prompt during boot due to floating RX pins. This patch
fixes the problem for us (and probably others). It is similar in
nature to linux kernel commit 138c2b2f175b ("ARM: dts: at91: fixes
dbgu pinctrl, set pullup on rx, clear pullup on tx")

While at it, remove pointless waste of power that the pullup of
the TX pins causes and fix the signal comments for SAMA5D4.

sizes.h: move include/sizes.h to include/linux/sizes.h ...

This file originates in Linux.  Linux has it under include/linux/
directory since commit dccd2304cc90.
Let's move it to the same place as well in barebox.

This commit was generated by the following commands:

  find -name '*.[chS]' | xargs sed -i -e 's:<sizes.h>:<linux/sizes.h>:'
  git mv include/sizes.h include/linux/

macb: rename platform data ...

The macb/gem core is used by the Zynq SoC.  In preparation of sharing
the macb driver between at91 and Zynq, rename the platform data to
'struct macb_platform_data', and move the definition to a common
location.
