spi: hisi-kunpeng: Delete the dump interface of data registers in debugfs

[ Upstream commit 7430764f5a85d30314aeef2d5438dff1fb0b1d68 ]

Due to the reading of FIFO during the dump of data registers in
debugfs, if SPI transmission is in progress, it will be affected
and may result in transmission failure. Therefore, the dump
interface of data registers in debugfs is removed.
