[PATCH v6 06/14] mfd: lm3533-core: Remove redundant pdata helpers

[Svyatoslav Ryhel <clamor95@gmail.com>]

The lm3533_set_boost_freq() and lm3533_set_boost_ovp() functions are used
only in lm3533_device_setup(), which in turn is only called by
lm3533_device_init(). Incorporate their code directly into
lm3533_device_init() to simplify driver readability.
