x86: crt0: Remove 'je copyDataDone' from CONFIG_XIP block

When CONFIG_SYS_POWER_DEEP_SLEEP is enabled, the _sys_soc_resume
function is called and the 'ZF' bit from EFLAGS register may be set
to 1. In that case, we end up wrongly jumping into 'copyDataDone'
label and no data is copied from ROM to RAM.

It seems this 'je' instruction is used without any previous comparison
operation which properly sets the ZF flag. Since 'ZF' initial value is
0, we never jump into 'copyDataDone' label. Also, this 'je' instruction
doesn't seem to be really required since, if %ecx is zero, no data will
be copied anyway.

That being said, this patch removes the 'je' instruction since it fixes
the bug described in the first paragraph and it doesn't affect the rest
of the crt0 execution.

Also, removes outdated information about section size and alignment.
