platform_get_irq() returns an error code, but the spi-xlp driver ignores
it and always returns -EINVAL. This is not correct and, prevents
-EPROBE_DEFER from being propagated properly.
Notice that platform_get_irq() no longer returns 0 on error:

Print and propagate the return value of platform_get_irq on failure.
This issue was detected with the help of Coccinelle.

ARCH_VULCAN arm64 platform (for Broadcom Vulcan ARM64 processors) has
been discontinued. Cavium's ThunderX2 CN99XX (ARCH_THUNDER2) will be
the next revision of the platform.
Update compile dependencies and ACPI ID to reflect this change. There
is not need to retain ARCH_VULCAN since the Vulcan processor was never
in production and ARCH_VULCAN will be deleted soon.

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.
Export the module alias information using the MODULE_DEVICE_TABLE() macro.
Before this patch:
$ modinfo drivers/spi/spi-xlp.ko | grep alias
alias: acpi*:BRCM900D:*
After this patch:
$ modinfo drivers/spi/spi-xlp.ko | grep alias
