`vnc_remove_queue` would waiting for new frame update request forever
even if the connection is lost, the updater thread wouldn't exit.
But the server thread will join updater thread before accept new client
connection, then we can't re-conncet to vnc server.

State of problem:
- Some drivers that do not support write operations (does not
have write handler or ioctl do not perform any write actions)
are registered with write permissions
- Some drivers that do not support read operation (does not
have read handler or ioctl do not perform any read actions)
are registered with read permissions
- Some drivers are registered with execute permissions
Solution:
- Iterate code where register_driver() is used and change 'mode'
parameter to reflect the actual read/write operations executed
by a driver
- Remove execute permissions from 'mode' parameter

Summary:
- I received an issue report that multiwebcam in Spresense SDK 2.4.0
has a problem with the Chrome browser
- Actually, the browser tries to establish 2 connections but
the multiwebcam can handle only 1 connection. And if accept() for
the second connection is delayed, the connection no longer exists
in the gs2200m hardware
- This commit fixes this issue by checking if the cid is valid or not.
Impact:
- gs2200m driver only
Testing:
- Tested with spresense:wifi_smp

since ISIG belong local mode flags not input mode flags,
but local mode isn't implemented by pty driver yet.

since both values have to typedef pipe_ndx_t to uint16_t,
it doesn't make sense to limit the size smaller than 65535

Some PPG devices have 4 ADCs to output quad-channel PPG values while some of them only have 2 ADCs to output dual-channel PPG.
To deal the case above, the type PPGD(PPG of Dual-channel) takes the place of former type PPG, which also have 2-channel PPG outputs. Type PPGQ (PPG of Quad-channel) is new for 4-ADC-PPG. Both types have contained new data "gain" to indicate ADC gains of each PPG channel, for the reason that the gains may vary during automatical optical adjustments.

iSerialNumber field in the device descriptor can be used to determining the
board when multiple boards connected to the same host. So add feature to change
serial string by board unique ID dynamically.
To use this feature, user must be implement the board_usbdev_serialstr() logic.
