The value of device_get_dma_attr() is only relevenat for ARM64 and CCP
devices to configure the value of the axcache attribute used to access
memory by the coprocessor. None of this applies to the platform psp so
skip it.

Move this into the sp_get_plat_version() function.
sp->dev_vdata = sp_get_plat_version(pdev);
And I probably should have made this comment in the previous patch, but
you should probably spell out platform here.

Just a nit but I'd prefer to see this as:
if (attr == DEV_DMA_NOT_SUPPORTED && !sp_platform->is_platform) {
The diff is easier to see that way.
Thanks,
