add support for OBUS PLL buckets

p9_frequency_buckets.H
p9.obus.pll.scan.initfile
  document and support base frequencies
    1611 MHz - 25.78G, 156.25 MHz ref
    1250 MHz - 25G, 156.25 MHz ref
    1200 MHz - 19.2G, 133.33 MHz ref

pervasive_attributes.xml
  define ATTR_OB[0123]_PLL_BUCKET to hold encoded ring bucket select value

nest_attributes.xml
  define ATTR_FREQ_O_MHZ array to hold per chiplet OBUS frequency
  retain ATTR_FREQ_A_MHZ to serve as FBC A link frequency indicator

p9_setup_sbe_config.C
p9_sbe_attr_setup.C
  transmit bucket selection through FSP/BMC->SBE mailbox
  encode OBUS bucket selects in Scratch Reg2 bits 24:31

p9_sbe_chiplet_pll_initf.C
p9_sbe_chiplet_pll_initf_errors.xml
  scan correct ring image based on bucket selector attributes

p9_ringId.C
p9_ringId.H
p9_ring_id.h
  accomodate three copies of obX_pll_bndy (use ID previously reserved for
  obX_pll_func, which should not be necessary to scan init)

scan_procedures.mk
generateWrapper.pl
  initCompiler infrastructure changes to support build of bucket data

p9.fbc.ab_hp.scom.initfile
p9.fbc.ioo_tl.scom.initfile
p9_tod_setup.C
  updates to handle A,O frequency attribute changes
