Vladimir Kondratyev 3ca6000f2a ig4(4): Fix SDA HOLD time set too low on Skylake controllers
Execution of "Soft reset" command (IG4_REG_RESETS_SKL) at controller init
stage sets SDA_HOLD register value to 0x0001 which is often too low for
normal operation.

Set SDA_HOLD back to 28 after reset to restore controller functionality.
