avoid to expand the code space to much.
Note: the size will increase 192 bytes on stm32_tiny:nsh.

Summary:
- I noticed that the hello (ELF) application causes a memory leak.
- Finally, I found that the data section is not deallocated.
- This commit fixes this issue.
Impact:
- None
Testing:
- Tested with spresense:wifi_smp, rv-virt:nsh64, sabre-6quad:netnsh

since IFF_DOWN is only used for request, not for status. Instead,
IFF_UP should be used to query the netdev status. The IFF_DOWN
related macros are also removed to avoid the confuse.

If CONFIG_SMARTFS_MULTI_ROOT_DIRS is enabled and dev->partname is not empty,
dev->rwbuffer is an uninitialized variable and register_blockdriver is called.
This commit adds RX DMA support to serial driver. The DMA is currently
supported only for USART peripherals, not for UART. It uses two circular
buffers which size can be setup by SAMV7_SERIAL_RXDMA_BUFFER option.
The idle bus interrupt is enabled to ensures data are read even if the
buffer is not yet full. The timeout can be setup by
SAMV7_SERIAL_DMA_TIMEOUT option.
This adds support only for RX transfers.

This commit adds functions sam_dmarxsetup_circular() and
sam_dmarxstart_circular() that create API for operating with two or more
circular buffers. This can be used for DMA operation with serial driver
or ADC where ping pong buffers are required to successfully transfer the
data at high speed.

This commit enhances SAMV7 serial driver with RS-485 mode available to
USART peripherals. The hardware automatically sets RTS pin high when
data are transfered and low then no transfer occurs. Only USART peripherals
support this mode, UART peripherals do not.
This mode can be enabled by configuration option SAMV7_USARTx_RS485MODE.

Summary:
- Since the stack coloration is done for every 32bits
this function should be done in the same way.
Impact:
- None
