Tony Lindgren 4115c053a3 phy: mapphone-mdm6600: Fix write timeouts with shorter GPIO toggle interval ... commit 46b7edf1c7 upstream. I've noticed that when writing data to the modem the writes can time out at some point eventually. Looks like kicking the modem idle GPIO every 600 ms instead of once a second fixes the issue. Note that this rate is different from our runtime PM autosuspend rate MDM6600_MODEM_IDLE_DELAY_MS that we still want to keep at 1 second, so let's add a separate define for PHY_MDM6600_IDLE_KICK_MS.
