nicintel_spi.c: Refactor singleton states into reentrant pattern
Move global singleton states into a struct and store within
the bitbang_spi_master data field for the life-time of the driver.
This patch also drops `nicintel` prefix from spi master struct member.
This is one of the steps on the way to move spi_master data
memory management behind the initialisation API, for more
context see other patches under the same topic "register_master_api".
