epiphany/gas: Update expected test results for 0 offset loads

In commit 02a79b89fdeadccb67048291e6c2a1e5ce6ad623 some of the load
instructions with a zero offset (where the offset is not mentioned) were
marked as NO-DIS, meaning that the disassembler must display the offset,
even though it is zero.

This change seems a little strange to me as it was only applied to some
loads, not all, and the same change was not applied to the stores.

However, I'm reluctant to revert a specific change to the assembler,
when the output is obviously correct.  With this commit then I simply
bring the expected assembler test results into line with what is
actually produced.

gas/ChangeLog:

	* testsuite/gas/epiphany/addr-syntax.d: Add explicit 0 offset to
	some load instructions.
	* testsuite/gas/epiphany/allinsn.d: Likewise.
	* testsuite/gas/epiphany/regression.d: Likewise.
