PCI: mobiveil: fix 5.7 merge errors

Fix errors in the mobiveil version that was merged in 5.7 kernels:
- the type of "root_bus_nr" was changed from "u8" to "char", but
  it is compared to values that are typed as "unsigned char".
  Depending whether a platform has "char" as signed or unsigned,
  this may not do what is intended.

- ls_pcie_g4_reinit_hw() now returns a success/failure value, and
  follows the Linux style of return 0 on success and -ve errno on
  failure.  However, the testing in ls_pcie_g4_reset() expects 0
  on failure, so we won't call ls_pcie_g4_enable_interrupt() except
  if ls_pcie_g4_reinit_hw() has failed - which is likely not what
  was intended.
