Move HEART specific parts of mach-ip30/irq.h to asm/sgi/heart.h and IP30
specific parts to sgi-ip30/ip30-common.h.

BCM1250_M3_WAR is depending on CONFIG_CONFIG_SB1_PASS_2_WORKAROUNDS.
So using this option directly lets and remove define.

SB1250 uart bug is related to PASS 2 workarounds. Use config
CONFIG_SB1_PASS_2_WORKAROUNDS directly and get rid of SIBYTE_1956_WAR.

Neither MIPS4K_ICACHE_REFILL_WAR nor MIPS_CACHE_SYNC_WAR are implemented,
so removing defines for it won't change anything.

MIPS MMIO macros for byteswapping from/to hardware endianness are a bit
tricky because they use cpu_to_le{16,32,64}() in both directions.
This generates a lot of questions from sparse as __le{16,32,64} types
are 'restricted' and direct cast is forbidden in order to prevent messing
up the byteorder.
As MMIO ops are used in almost every single driver, this leads to console
flooding and complicates bug hunting.
We could fix it in a more proper way, i.e. separate from device /
to device byteswap macros and expand __BUILD_MEMORY_*(), but this seems
redundant and will produce code duplication.
Instead, just expand the existing *ioswab*() macros with forced
typecasting to stop floods.

There are some common header files which are referenced locally
with #includenext method, includenext is tricky method and only
used on mips platform.
This patech removes includenext method, replace it with defailed
pathname prefix for header files.
This patch passes to compile on all mips platform with defconfig,
and is verified on my loongson64 box.
Changes:
--------
v2:
- Fix compiling issue on malta platform
