Hi all,
This patch series improves user experience for
samples/timers/hpet_example

PATCH 1/2 --> Add support to print help text if user does not provide
required arguments.

PATCH 2/2 --> add help text in timers Kconfig

Testing:
I have tested the changes on x86 with hpet device as follows.

1. Build the sample program
$ gcc hpet_example.c -o hpet_example

2. Run hpet program with no args

$ ./hpet_example
-hpet: requires command
Format: hpet_example <command> </dev/device_name>
Supported commands:
open-close
info
poll
fasync

Example: $ ./hpet_example info /dev/hpet

3. Run and verify hpet commands on /dev/hpet

$ sudo ./hpet_example info /dev/hpet
-hpet: executing info
hpet_info: hi_irqfreq 0x0 hi_flags 0x10 hi_hpet 0 hi_timer 0
