net: hns3: refactor dump reg of debugfs 

Currently, the debugfs command for reg is implemented by
"echo xxxx > cmd", and record the information in dmesg. It's
unnecessary and heavy. To improve it, create some files
"bios_common/ssu/igu_egu/rpu/ncsi/rtc/ppp/rcb/tqp/mac" for it,
and query it by command "cat xxx", return the result to
userspace, rather than record in dmesg.

The display style is below:
$ cat bios_common
BP_CPU_STATE: 0x0
DFX_MSIX_INFO_NIC_0: 0xc000
DFX_MSIX_INFO_NIC_1: 0x0
DFX_MSIX_INFO_NIC_2: 0x0
DFX_MSIX_INFO_NIC_3: 0x0
DFX_MSIX_INFO_ROC_0: 0xc000
DFX_MSIX_INFO_ROC_1: 0x0
DFX_MSIX_INFO_ROC_2: 0x0
DFX_MSIX_INFO_ROC_3: 0x0
