arm: cpu: Add optional CMOs by VA
Exposing set/way cache maintenance to a virtual machine is unsafe, not
least because the instructions are not permission-checked but also
because they are not broadcast between CPUs. Consequently, KVM traps and
emulates such maintenance in the host kernel using by-VA operations and
looping over the stage-2 page-tables. However, when running under
protected KVM, these instructions are not able to be emulated and will
instead result in an exception being delivered to the guest.
Introduce CONFIG_CMO_BY_VA_ONLY so that virtual platforms can select
this option and perform by-VA cache maintenance instead of using the
set/way instructions.

- Split header size and image data offset into two variables (headersz and
*dataoff).
- Change image_headersz_v0() and add_binary_header_v1() functions to return
real (unaligned) header size instead of image data offset.
- On every place use correct variable (headersz or *dataoff)
After these steps variable headersz is correctly filled into the
