hpet: Make cmd parameter of hpet_ioctl_common() unsigned
The value passed by the two callers of the function is unsigned anyway.
Making the parameter unsigned fixes the following warning when building
with clang:
drivers/char/hpet.c:588:7: error: overflow converting case value to switch condition type (2149083139 to 18446744071563667459) [-Werror,-Wswitch]
case HPET_INFO:
^
include/uapi/linux/hpet.h:18:19: note: expanded from macro 'HPET_INFO'
^
include/uapi/asm-generic/ioctl.h:77:28: note: expanded from macro '_IOR'
^
include/uapi/asm-generic/ioctl.h:66:2: note: expanded from macro '_IOC'
