!600 The driver supports PCIe 4 TB BAR device allocation.

Merge Pull Request from: @lujunhuaHW 
 

PCI: Support BAR sizes up to 8TB：
Current kernel reports that BARs larger than 128GB, e.g., this 4TB BAR, are disabled: pci 0000:01:00.0: disabling BAR 4: [mem 0x00000000-0x3ffffffffff 64bit pref] (bad alignment 0x40000000000)
Increase the maximum BAR size from 128GB to 8TB for future expansion.

Detailed Description: 
The 1813 EP device requires 4 TB BAR space to meet the address requirements on the card side. A certain amount of space is reserved for future expansion. The space is increased to 8 TB.
