When firmware assert, it need coredump to analyze, this patch will collect the register and memory info for sdio chip. The coredump configuration is different between PCIE and SDIO for the same reversion, so this patch add bus type to distinguish PCIE and SDIO chip for coredump. It has 2 type to dump firmware: fastdump and slowdump. Fastdump is not support in old version firmware, if this, ath10k will select slowdump for it. If firmware support fastdump, ath10k will select fastdump for it. Version WLAN.RMH.4.4.1-00017-QCARMSWPZ-2 of firmware begin to support fastdump. For slow dump, ath10k_sdio_hif_diag_read can not be used, the diag window has a limit value, it is 4 bytes and the dump's buffer length is larger than it, it will trigger error. So this patch add ath10k_sdio_read_mem to read 4 bytes for each time. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00018-QCARMSWP-1.
