With the cursor before the first such line,

.,$s/ *;$//

will delete any ';' at the end of lines, plus the immediately preceding
spaces, to the end of the file. To keep the spaces, omit the " *".

Alignment is trickier, and can vary depending on your tabstop setting.
You could set tabstop=15, if i_sram_raddr0 is the longest column-two
word, and substitute all space sequences with a single tab, then the ';'
will be aligned:

:set noexpandtab
:set tabstop=15
:.,$s/ */\t/g

That works here, on your lines, at the cost of greater spacing between
the first two columns as well. That could be reduced subsequently, if
sufficiently important.

The " *" idiom for "any non-zero number of spaces" can be expressed in
more standardised regex if sufficient Vim "magic" is turned on:

:.,$s/\v +/\t/g

I.e. " +" is "any non-zero number of spaces" in its simplest form.
Vim fails at that, by defaulting to obsolete BRE, rather than modern ERE.
