If LPC BT driver is registered ahead of lpc-ctrl module, LPC BT hardware block will be enabled without heart beating of LCLK until lpc-ctrl enables the LCLK. This issue causes improper handling on host interrupts when the host sends interrupts in that time frame. Then kernel eventually forcibly disables the interrupt with dumping stack and printing a 'nobody cared this irq' message out. To prevent this issue, all LPC sub drivers should enable LCLK individually so this patch adds 'clocks' property as one of required properties to enable the LCLK by the LPC IBT driver. Note: dtsi change in this patch series should be applied along with, and dtbs should be re-compiled after applying this series since it's adding a new required property otherwise the driver will not be probed correctly.
