s5k3l6xx: use power_on/off timings similar to s5k6a3
On one, but not all Evergreen device I see power_on() failing, resulting in
[ 8.132813] s5k3l6xx 3-002d: using default 24000000 Hz clock frequency
[ 8.132837] s5k3l6xx 3-002d: GPIO lookup for consumer rstn
[ 8.132843] s5k3l6xx 3-002d: using device tree for GPIO lookup
[ 8.132931] s5k3l6xx 3-002d: probe i2c ffff0000010e4800
[ 8.200983] s5k3l6xx: i2c_read: error during transfer (-6)
Using a different power_on() sequence inspired by other Samsung sensor drivers like s5k6a3, makes things work for my devices.
