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.

======
Spresense is a compact development board based on Sony’s power-efficient
multicore microcontroller CXD5602. It allows developers to create IoT
applications in a very short time and is supported by the Arduino IDE as well
as the more advanced NuttX based SDK.
- Integrated GPS
The embedded GNSS with support for GPS, QZSS and GLONASS enables applications
where tracking is required.
- Hi-res audio output and multi mic inputs
Advanced 192kHz/24 bit audio codec and amplifier for audio output, and
support for up to 8 mic input channels.
- Multicore microcontroller
Spresense is powered by Sony's CXD5602 microcontroller (ARM® Cortex®-M4F × 6
cores), with a clock speed of 156 MHz.
