dpll: zl3073x: recognize the ZL30643 chip ID (0x0E3B)

Browse Source 
The Microchip ZL30643 is a 3-channel ZL3064x line-card part that is
register compatible with the ZL30733. Only the runtime chip-ID table
needs the 0x0E3B entry so the probe resolves the channel count (3)
and flags.

The ZL3073X_FLAG_REF_PHASE_COMP_32 flag applies unchanged: the
ref_phase path
  dpll_meas_ctrl::en -> ref_phase_0P/0N
  -> ref_phase_offset_compensation -> ref_phase_err_read_rqst
is identical between ZL3064x and ZL3073x. No new device flag is needed.

Test: once register, for instance, we get:

  devlink dev param set spi/spi0.0 name clock_id value 3733 cmode driverinit
  devlink dev reload spi/spi0.0
  devlink dev param set spi/spi2.1 name clock_id value 3643 cmode driverinit
  devlink dev reload spi/spi2.1

  dpll device show | grep clock-id
    clock-id: 3733
    clock-id: 3733
    clock-id: 3733
    clock-id: 3643
    clock-id: 3643
    clock-id: 3643
