Re-check RX queue status after uart_enablerxint() and before blocking
the reading task on the receive semaphore. cdcacm (and maybe other UART
drivers) can push buffered data into the receive queue during
uart_enablerxint(), leading to a blocked task while data is already
available.

If size_t != uint32_t, this can give a build error:

Add basic sample rate conversion to the CXD56 Spresense audio
driver using libsamplerate. Currently conversion is only done
during playback and all output is fixed at 48 kHz.
Issues:
- 16 kHz SRC has glitches (unless data dump is enabled)
- 44.1 kHz SRC gets stuck

Note: The chips' auto-scanning feature is not supported in this revision.
1.use userspace buffer rather than intermediate buffer of upperhalf driver
2.support block and non-block ways.

When audio fails it is usefull to have I2S transfer errors in place
to be able to track the issue

Summary:
- This commit enables gs2200m driver to get IWNWID/IWFREQ/IWSENS information
Impact:
- Affects gs2200m only
Testing:
- Tested with spresense:wifi
The sendblk function was missing NOSTOP on the first msg of the
i2c transaction. This could cause an extra STOP to be inserted
in the transaction.
The driver uses up_mdelay for some timing where it should be
using a sleep.
