Due to some renaming, we ended up with the "indirect iomem"
naming in Kconfig, following INDIRECT_PIO. However, clearly
I missed following through on that in the ifdefs, but so far
INDIRECT_IOMEM_FALLBACK isn't used by any architecture.

lib/logic_iomem: Fix operation on 32-bit

lib/logic_iomem: Fix operation on 32-bit
On 32-bit, the first entry might be at 0/NULL, but that's
strange and leads to issues, e.g. where we check "if (ret)".
Use a IOREMAP_BIAS/IOREMAP_MASK of 0x80000000UL to avoid
this. This then requires reducing the number of areas (via
MAX_AREAS), but we still have 128 areas, which is enough.

lib: add iomem emulation (logic_iomem)
Add IO memory emulation that uses callbacks for read/write to
the allocated regions. The callbacks can be registered by the
users using logic_iomem_alloc().
To use, an architecture must 'select LOGIC_IOMEM' in Kconfig
and then include <asm-generic/logic_io.h> into asm/io.h to get
the __raw_read*/__raw_write* functions.
Optionally, an architecture may 'select LOGIC_IOMEM_FALLBACK'
in which case non-emulated regions will 'fall back' to the
various real_* functions that must then be provided.
