regulator: sm5703: Remove because it is unused and fails to build

This file does not compile because <linux/mfd/sm5703.h> is missing.
In KConfig, it depends on MFD_SM5703.

Both MFD_SM5703 and the missing include rely on another patch that never
got merged. The last iteration related to this patch is [1].

So remove this dead-code and undo commit e8858ba89ca3 ("regulator:
sm5703-regulator: Add regulators support for SM5703 MFD")
