staging: wfx: load the firmware faster

Browse source

During the loading of the firmware, the WFX_DCA_GET register provide the
number available bytes in the receiving buffer. It is not necessary to
access to the WFX_DCA_GET after sent of each firmware fragment.

This patch allows to send the firmware:
  - in 64ms instead of 130ms using SDIO bus
  - in 78ms instead of 115ms using SPI bus
