net: microchip: vcap: Add typegroup table terminators in kunit tests

[ Upstream commit f164b296638d1eb1fb1c537e93ab5c8b49966546 ]

VCAP API unit tests fail randomly with errors such as

   # vcap_api_iterator_init_test: EXPECTATION FAILED at drivers/net/ethernet/microchip/vcap/vcap_api_kunit.c:387
   Expected 134 + 7 == iter.offset, but
       134 + 7 == 141 (0x8d)
       iter.offset == 17214 (0x433e)
   # vcap_api_iterator_init_test: EXPECTATION FAILED at drivers/net/ethernet/microchip/vcap/vcap_api_kunit.c:388
   Expected 5 == iter.reg_idx, but
       iter.reg_idx == 702 (0x2be)
   # vcap_api_iterator_init_test: EXPECTATION FAILED at drivers/net/ethernet/microchip/vcap/vcap_api_kunit.c:389
   Expected 11 == iter.reg_bitpos, but
       iter.reg_bitpos == 15 (0xf)
   # vcap_api_iterator_init_test: pass:0 fail:1 skip:0 total:1

Comments in the code state that "A typegroup table ends with an all-zero
terminator". Add the missing terminators.

Some of the typegroups did have a terminator of ".offset = 0, .width = 0,
.value = 0,". Replace those terminators with "{ }" (no trailing ',') for
consistency and to excplicitly state "this is a terminator".
