Subject: [PATCH v7 02/28] x86/asm/suspend: drop ENTRY from local data

ENTRY was intended for functions and shall be paired with ENDPROC.
ENTRY also aligns symbols which creates unnecessary holes here between
data.

So drop ENTRY from saved_eip in wakeup_32 and many saved_* in wakeup_64,
as these symbols are local only.

We could use SYM_DATA_LOCAL for these symbols, but it was discouraged
earlier [1].
