6.6-stable review patch. If anyone has any objections, please let me know.

From: Yihang Li <liyihang9@xxxxxxxxxx>
[ Upstream commit 73e33f969ef05328766b23a99b2c07bfff765009 ]
In function debugfs_debugfs_snapshot_global_reg_v3_hw() it uses
debugfs_axi_reg.count (which is the number of axi debugfs registers) to
acquire the number of global debugfs registers.
Use debugfs_global_reg.count to acquire the number of global debugfs
registers instead.
