[PATCH] spi: sunplus-sp7021: use devm_reset_control_get_exclusive_deasserted()

[Felix Gu <ustc.gu@gmail.com>]

Use devm_reset_control_get_exclusive_deasserted() to replace the
explicit reset acquisition, deassertion, and cleanup action registered
with devm_add_action_or_reset().

This simplifies reset handling and removes the custom reset assertion
callback while preserving reset assertion during cleanup.
