Subject: [PATCH] sh: pci: Remove unused variable in SH-7786 PCI Express code

Addresses the following warning when building sdk7786_defconfig:

arch/sh/drivers/pci/pcie-sh7786.c:34:22: warning: 'dma_pfn_offset' defined but not used [-Wunused-variable]
   34 | static unsigned long dma_pfn_offset;
      |                      ^~~~~~~~~~~~~~

Fixes: e0d072782c73 ("dma-mapping: introduce DMA range map, supplanting dma_pfn_offset")
