powerpc/corenet: fix compile error when CONFIG_SYS_NO_FLASH is defined
ENV location compile logic is wrong, and when CONFIG_SYS_NO_FLASH is defined
and non-NOR u-boot is building, it will cause compile error. Also, add
CONFIG_SYS_FLASH_USE_BUFFER_WRITE for p2041, which will improve NOR flash

1. Remove useless length alignment check. We get actual transfer
length not the size of the underlying buffer so it's perfectly
valid for it to be unaligned.
2. Move flush_dcache_range() out of while loop or it will
flush too much.
3. Don't try to fix buffer address before calling invalidate:
if it's unaligned it's an error anyway so let cache subsystem
cry about that.
4. Fix end buffer address to be cacheline aligned assuming upper
layer reserved enough space. This is potentially dangerous
operation so upper layers should be careful about that.
