PCI: mt7621: Fix string truncation in mt7621_pcie_parse_port()

Browse Source 
The following warning appears when driver is compiled with W=1.

CC      drivers/pci/controller/pcie-mt7621.o
drivers/pci/controller/pcie-mt7621.c: In function ‘mt7621_pcie_probe’:
drivers/pci/controller/pcie-mt7621.c:228:49: error: ‘snprintf’ output may
be truncated before the last format character [-Werror=format-truncation=]
228 |         snprintf(name, sizeof(name), "pcie-phy%d", slot);
    |                                                 ^
drivers/pci/controller/pcie-mt7621.c:228:9: note: ‘snprintf’ output between
10 and 11 bytes into a destination of size 10
228 |         snprintf(name, sizeof(name), "pcie-phy%d", slot);
    |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Clean this up increasing destination buffer one byte.
