spi: axi-spi-engine: simplify driver data allocation

Browse Source 
[ Upstream commit 9e4ce5220eedea2cc440f3961dec1b5122e815b2 ]

This simplifies the private data allocation in the AXI SPI Engine driver
by making use of the feature built into the spi_alloc_host() function
instead of doing it manually.
