When DEBUG_SPI is included in the debug log level wl1271_spi_reset()
will dump the already freed memory instead of the SPI buffer.
This bug was spotted by the semantic patch tool coccinelle using the
script found at scripts/coccinelle/free/kfree.cocci.

All files name prefix removed due to the fact that wl12xx driver supports
wl1271 and wl1273.
Also the definition in Kconfig and header files changed respectively.

In the wl1271 implementation, we need to read memory from the register
partition using fixed addresses. This change adds the possibility to request
fixed address when calling wl12xx_spi_read() or wl12xx_spi_reg_read().

In some cases we need to read more than 32 bits from the register area.
These functions were added to support that, like the existing
wl12xx_spi_mem_read() and wl12xx_spi_mem_write() already do for large blocks
in the memory area.
