[PULL 07/23] tests/functional/aspeed: Move I2C test into shared helper for AST2700 reuse

["Cédric Le Goater" <clg@redhat.com>]

From: Jamin Lin <jamin_lin@aspeedtech.com>

Move the I2C test case into a common helper function (do_ast2700_i2c_test) so it
can be reused across multiple AST2700-based test cases. This reduces duplication
and improves maintainability.
