This patch is a preceding step for making common lp55xx init function.
LP5521_REG_R_CURRENT register code moved:
Chip specific code moved from lp5521_init_device() to lp5521_configure().
Remove engine init function:
LP5521 has internal program engines which are used for running LED patterns.
(blinking, ramp up/down and other emotional visual effects)
Engine initialization is done by reset command in lp5521_init_device().
Remove this duplicate code.
Return code:
Do not use 'OR' arithmetic for the result.
If some error occus, just return it.
Enable latency:
Use explicit named function, lp5521_wait_enable_done().
According to the datasheet, 500us is guaranteed time.
Thus wait time is changed from 1000us to 500us.
