nios2: fix cached mode in clearing the BSS
As the generic board runs in cached mode, it should not use
"stwio" which bypass the cache.

nios2: change virt_to_phys to use physaddr_mask in global data
As virt_to_phys() is used a lot in DMA transfer, change it
to use physaddr_mask in global data. This will save an "if"
statement and get a little faster.

nios2: convert cache flush to use dm cpu data
Convert cache flush to use dm cpu data.
The original cache flush functions are written in assembly
and use CONFIG_SYS_{I,D}CACHE_SIZE... macros. It is difficult
to convert to use cache configuration in dm cpu data which is
extracted from device tree.
The cacheflush.c of Linux nios2 arch uses cpuinfo structure,
which is very close to our dm cpu data. So we copy and modify
it to arch/nios2/lib/cache.c to replace the old cache.S.

nios2: set default cache configuration in start.S
Set default icache and dcache configuration for start.S.
We want to remove the CONFIG_SYS_{I,D}CACHE_SIZE...
configuration macros. As we are just barely starting from
reset, there is no luxury of device tree.
We will set some maximum cache configuration so that it will
work for most configurations. This is used only in this
start.S. The speed penalty is only once here.
After start up, during board initialization, cpu information
will be extracted from device tree. Then cache flush operations
will have correct cache configurations.

Add ioremap() to map physical address to uncached virtual
address. We need this to convert the reg address from the
device tree.
The order of headers inclusion in interrupts.c is changed
because common.h will include board header that contains
IO_REGION_BASE.
In the future, the IO_REGION_BASE should be decided from
the device tree.
