util/ifdtool: Fix SPI frequency as per Gen11 SPI flash guide
BUG=b:153888802 TEST=Able to list correct SPI frequency as per TGL SPI flash guide Without this CL : Found Component Section FLCOMP 0x093030f6 Dual Output Fast Read Support: not supported Read ID/Read Status Clock Frequency: 33MHz Write/Erase Clock Frequency: 33MHz Fast Read Clock Frequency: 33MHz Fast Read Support: supported Read Clock Frequency: 20MHz With this CL : Found Component Section FLCOMP 0x093030f6 Dual Output Fast Read Support: not supported Read ID/Read Status Clock Frequency: 50MHz Write/Erase Clock Frequency: 50MHz Fast Read Clock Frequency: 50MHz Fast Read Support: supported Read Clock Frequency: 20MHz Signed-off-by: Subrata Banik <subrata.banik@intel.com> Change-Id: Id0a0a0cbd948ef8334cf522c09e881b464e87f0e Reviewed-on: https://review.coreboot.org/c/coreboot/+/44819 Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
