Increase the size of the string buffer to avoid potential truncation in
dw_pcie_edma_irq_verify().
This fixes the following build warning when compiling with W=1:
drivers/pci/controller/dwc/pcie-designware.c: In function ‘dw_pcie_edma_detect’:
drivers/pci/controller/dwc/pcie-designware.c:989:50: warning: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size 3 [-Wformat-truncation=]
989 | snprintf(name, sizeof(name), "dma%d", pci->edma.nr_irqs);
| ^~

Changes since v2:
-Simply increase the size of the string buffer instead of chaning the
print format specifier.
