Do not export the ltq_reset_cause() and ltq_boot_select() function any more. ltq_reset_cause() was accessed by the watchdog driver before to see why the last reset happened, this is now done through direct access of the register over regmap. The bits in this register are anyway different between the xrx200 and the falcon SoC. ltq_boot_select() is not used any more and was used by the flash drivers to check if the system was booted from this flash type, now the drivers should depend on the device tree only.
