ichspi: Add support for C740 PCH

Browse Source 
Clean commit 51e1d0e4b7
'Add support for Intel Emmitsburg PCH' which broke
CHIPSET_5_SERIES_IBEX_PEAK detection and which assumes C740 is the same
as C620, while its more a close relative to Intel's H570 PCH.

Based on Intel SPI Programming Guide #619386.

Test: Run on Intel ArcherCity CRB with Intel's C741 PCH
      using the 'internal' programmer.
Test: Run on BMC and accessed the SPI flash chip over
      'linux_mtd' programmer.
