This commit adds two new IOCTL commnands for ADC driver. Command
ANIOC_RESET_FIFO resets FIFO head and tail which causes the driver
to wait for the new data to be received. Calling this command before
reading ADC data in user space ensures that the read data are newly
sampled.
Command ANIOC_SAMPLES_ON_READ return the number of read channels in
the buffer. This can be useful in nonblocking mode when the application
needs to get the samples received before the app was started.
Both IOCTL commands are used only in generic driver section only and do
not have any effect on existing architecture specific drivers.

This command enables the application to perform the final steps of the
booting process prior to finally switching the execution to another
firmware image.

Number of configured ADC channels is currently only defined in board
level section, typically in xxx_adc.c file. This commit introduces
ioctl command ANIOC_GET_NCHANNELS that returns the number of configured
channels which is determined by the driver code. The change can allow the
applications to be more flexible when it comes to multiple ADC devices
with different number of configured channels.

PWM drivers currently use channel number 0 for the channels that are not
used by the application. This commit adds number -1 which indicates that
all following channels are not configured and that the loop can be broken.

BOARDIOC_SWITCH_BOOT is required to communicate the boot partition from
userspace (OTA subsystem) to board. It can be used to change the system
boot behavior. So it's useful for A/B boot or even single boot case.
For the board support A/B boot case:
1. Download the new image from the sever
2. Write the new image to the alternative partition
3. Call BOARDCTL_SWITCH_BOOT to the alternative system
For single boot partition case:
1. Download the new image from the sever
2. Call BOARDCTL_SWITCH_BOOT and reboot to a small system
3. Write the new image to the main partition in the small system
4. Call BOARDCTL_SWITCH_BOOT again to the main system
