This patch uses debugfs_regset32 interface to create the registers dump
file. Use it instead of creating a generic debugfs file with manually
written read callback function.
With these entries, users can check all the SPI controller registers
during run time.

Fix warning Woverflow on type conversion reported on x86_64:
drivers/spi/spi-hisi-kunpeng.c:361:9: warning: conversion from 'long unsigned int' to 'u32'
{aka 'unsigned int'} changes value from '18446744073709551600' to '4294967280' [-Woverflow]
The registers are 32 bit, so fix by casting to u32.

This driver supports SPI Controller for HiSilicon Kunpeng SoCs. This
driver supports SPI operations using FIFO mode of transfer.
DMA is not supported, and we just use IRQ mode for operation completion
notification.
Only ACPI firmware is supported.
