loadenv: Do not depend on normalise_path() ...

normalise_path() will go away, so do without it.

ls: Do not depend on normalise_path() ...

When we want to show a directory we want to show the path
ls is passed, not the normalised one.

glob: do not unnecessarily opendir() a directory ...

opendir() can trigger automounts, so do not use it when the
pattern we examine doesn't have any wildcards.

fs: Fix finding correct directory for mkdir/rmdir ...

When there are links in the path mkdir/rmdir are called with then
canonicalize_path is needed which resolves the links.

fs: Move mem_write/mem_read to devfs-core ...

fs.c is already heavily filled with code. Move mem_write/mem_read
to devfs-core where it fits better.

fs: Add super_operations ...

Add a struct super_operations we can use later when we get a fs
implementation closer to Linux. Only add the functions we'll likely
need though.

Remove code that was added to UBIFS for U-Boot but that is not needed
for barebox.

ubifs: remove dead code ...

Remove stuff that was added to UBIFS for U-Boot which we do not need
because we already have it in the Linux header files.

rename file_operations -> cdev_operations ...

Linux also has struct file_operations which are something different.
Rename our file_operations to cdev_operations which better matches
what we have.

ARM: aarch64: Make early MMU support work ...

Until now it was not possible to enable the MMU in PBL because
create_section needs memory allocations which are not available. With
this patch we move the early MMU support to a separate file and all
necessary aux functions to mmu_64.h. create_sections is reimplmented
for the early case to only create 1st level pagetables.

ARM: change mmu_early_enable() prototype ...

Change the arguements to type unsigned long which is suitable for both
arm32 and arm64. While at it move the prototype to arch/arm/include/.

ARM: create separate mmu_64.h file ...

cpu/mmu.h has nothing in common for the 32bit and 64bit variant. Make it
two separate files.

ARM: Create own cache.c file for aarch64 ...

cache.c does not work properly for aarch64. We create a struct cache_fns
using C preprocessor foo which assumes the existence of cache
maintenance operations with a certain name. These functions have other
names on aarch64. While we could fix this we do not need the automatic
cache function selection on aarch64 since here we only have one function
set.
Create a separate file and be done with this issue.
