Although the driver could work on this hardware, i.MX1 support
currently lacks the necessary clocks resulting in linker errors.

Some drivers use gpio_request/gpio_free. Currently no architecture
has code behind these functions. Provide static inline functions
for these and remvoe the at91 specific inline functions.

The LED core itself does not need gpio support, so remove include
so that it compiles on architectures without gpio support.

The 'off_t cur_ofs' variable was missed during the 64 bit conversion.
For the MEMGETBADBLOCK ioctl, a pointer to a loff_t is needed.
Also adjust the debug format strings.

Since this commit we interpret the argument to the bad block ioctls
as a pointer to a 64bit number:

| mtd: fix arguments to bad block ioctls
|
| In the Kernel the mtd ioctls expect a pointer to the offset, whereas
| barebox interprets the pointer itself as an offset. Since we want
| to add 64bit support for file sizes a pointer may not be sufficient,
| so align with the kernel and convert it to a pointer to the offset.

We now have a resource size for the ehci hccr register space. This
was assumed to be 0x40 in size. On OMAP though it is only 0x10 and
then the hccr resource conflicts with the hcor resource which results
in a non working ehci port on beagle and panda boards. This patch
adds a nonintrusive workaround, it limits the hccr resource to 0x10,
which then also works on OMAP.
Later we should drop the multiple resources for the ehci port and
make the resource as specified in the datasheets.
This is broken since:

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.

The dump generated by "md -w -s /dev/phy0"
suggests individual registers need to be
addressed by byte offset, not by register number.
E.g. to set the autonegotiation advertisement register
for 10Mbit only, use "mw -w -d /dev/phy0 8+2 0x0061".
The current mix of offset == register number, but
count == byte count is unintuitive.
Also, to be consistent with "md" on /dev/mem, round up
the count so "8+1" also works to access one register.
However, no attempt is made to do read-modify-write
single byte writes.

We do not need to invalidate the cache in the poll loop anymore
since the corresponding bit is now in a dma coherent area. Instead,
flush cache before hardware operation and invalidate afterwards. Put
the corresponding code inline since it's shorter.

There's no point in syncing them manually. Instead, use
dma_alloc_coherent and skip the manual flushing/invalidating.
