For Secure Boot v2 case, unsigned image is first padded to next 64K
aligned boundary and then a signature block of 4K gets appended. Thus
an app partition whose size is 4K aligned should be allowed here.
For Secure Boot v1 case, app partition size must be 64K aligned as the
signature block lies at the very end of 64K boundary.
