arm: at91: fix clock to mci1 for at91sam9263 ...

at91_add_device_mci() was missing configuration of PIOA6
when configuring mci1.
With this fix we can read data from SD card with at91sam9263ek,
when built without DT.
Building without a DT is required when we do a bootstrap build.

The other at91samxxx_devices was checked - only the 9263 was
missing the CLK configuration for mci1.

arm: at91: move irq_fixup to header file ...

This allows at91_rtt_irq_fixup() to be used outside
of the mach-at91/ directory.
Adjust all call sites to include the at91_rtt header.

Deleting one .c file is another nice side effect of this move.

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.

at91: add irq fixup ...

Some of the irq can still be on after a reset or power on as the IP are
powered by the backup power. This could lead to an interrupt dead lock
when the kernel boot. So disable them before booting.

resource: store 'end' instead of 'size' in struct resource ...

Storing the size instead of the resource end in struct resource was
a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously
leads to problems. 'end' on the other hand will never exceed
UINT[32|64]_MAX. Also this way we can express a iomem region covering
the whole address space.
