LoongArch's include/asm/addrspace.h uses SZ_32M and SZ_16K, so add
<linux/sizes.h> to provide those macros to prevent build errors:

Addresses should all be of unsigned type to avoid unnecessary conversions.

This feature depends on the kernel being relocatable.
Enable using single kernel image for kdump, and then no longer need to
build two kernels (production kernel and capture kernel share a single
kernel image).
Also enable CONFIG_CRASH_DUMP in loongson3_defconfig.

When enable GENERIC_IOREMAP, there will be circular dependency to cause
build errors. The root cause is that pgtable.h shouldn't include io.h
but pgtable.h need some macros defined in io.h. So cleanup those macros
and remove the unnecessary inclusions, as other architectures do.
