Improve gs2200m performance

* arch/arm/src/cxd56xx: Fix dma initialization in cxd56_dmac.c

    up_dma_initialize() must be used instead of up_dmainitialize()

    Signed-off-by: Masayuki Ishikawa <Masayuki.Ishikawa@jp.sony.com>

* drivers/wireless: Introduce CONFIG_WL_GS2200M_SPI_FREQUENCY

    Also, changed usleep(100) to up_udelay(100) to avoid invalid response.

* configs/spresense/wifi: Improve performance for webserver

    This commit changes followings.

      1. Enable SPI DMA for both TX and RX
      2. Increase SPI clock speed from 4MHz to 10MHz
      3. Increase buffer size for sendfile() from 512B to 1KB
      4. Enable sendfile() for webserver
