ath10k: print crc32 checksums for firmware and board files

To detect cases if the firmare or board file is corrupted or otherwise modified print crc32 value
of both. Now the output looks like:

ath10k_pci 0000:02:00.0: pci irq msi interrupts 1 irq_mode 0 reset_mode 0
ath10k_pci 0000:02:00.0: qca99x0 hw2.0 target 0x01000000 chip_id 0x003801ff sub 168c:0002
ath10k_pci 0000:02:00.0: kconfig debug 1 debugfs 1 tracing 1 dfs 1 testmode 1
ath10k_pci 0000:02:00.0: firmware ver 10.4.1.00030-1 api 5 features no-p2p crc32 d2901e01
