[ 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".
