m88rs2000: add m88rs2000_set_carrieroffset
commit 06af15d1b6f45c60358feab88004472e5428f01c upstream.
Set the carrier offset correctly using the default mclk values.
Add function m88rs2000_get_mclk to calculate the mclk value
against crystal frequency which will later be used for
other functions.
Add function m88rs2000_set_carrieroffset to calculate
and set the offset value.
variable offset becomes a signed value.
Register 0x86 is set the appropriate value according to
remainder value of frequency % 192857 calculation as
shown.
