Subject: [PATCH] rt2800pci: fix comment about register access

Registers used for indirect BBP and RF registers access are
respectively BBPCSR and RFCSR, also make it clear that all CSR
registers access goes through rt2x00pci_register_[read,write]()
methods.

* These indirect registers work with busy bits,

* the register while taking a REGISTER_BUSY_DELAY us delay
