net: qca_spi: Move reset_count to struct qcaspi

BugLink: https://bugs.launchpad.net/bugs/1864060
[ Upstream commit bc19c32904e36548335b35fdce6ce734e20afc0a ]

The reset counter is specific for every QCA700x chip. So move this
into the private driver struct. Otherwise we get unpredictable reset
behavior in setups with multiple QCA700x chips.

Fixes: 291ab06ecf67 (net: qualcomm: new Ethernet over SPI driver for QCA7000)
