Newly added cm_t335 was missed in commit 47ed5dd0 which
made ARM targets produce full ELF files. Fix its linker
script.
This change is binary-invariant when only .dynsym, .dynstr,
.dynamic, .plt, .interp and .gun sections are declared.
Sections .hash, .got.plt, .dynbss and .ARM.exidx are also
declared so that their (unused) content is moved out of the
u-boot binary.

This prevents references to _end from generating absolute
relocation records.
This change is binary invariant for ARM targets.

Can we do a follow-up series where we look at making some sort of "head"
and "tail" perhaps linker snippets we can #include for ARM? The top of
my head recollection is that we've usually just got a situation of
needing to shove a few non-standard objects up front in the binary, and
everything else is the same. Thanks!

The follow-up is actually in my todo list and I already have a patch
series going that way, along with another one factorizing the start.S
files in a similar vein.
