Input: HIL - various fixes for HIL drivers
- mark some structures const or __read_mostly
- hilkbd.c: fix uninitialized spinlock in HIL keyboard driver
- hil_mlc.c: use USEC_PER_SEC instead of 1000000
- hp_sdc: bugfix for request_irq()/free_irq() parameters, this prevented
multiple load/unload cycles as module
