v4:
- Add a new patch for original #1. We need to fix a typo first before
original #1 patch.

- For patch #2, replace redundant ocp_word_set_bits() with ocp_word_w0w1().

v3:
- For patch #1, fix the issue identified by the AI review.
In v2, ocp_byte_set_bits() was used to update the USB_LPM_CTRL register.
However, since its function only perform a bitwise OR operaion, it fails
to clear the old bits when updating a multi-bit field like LPM_TIMER.
Therefore, use ocp_write_byte() to maintain the original direct-write
semantics.

- For patch #2, fix the line length exceeding 80 columns

v2:
For patch #2, remove variable set but not used from r8153_init(),
r8153b_init() and r8153c_init()

v1:
Add bitwise operaion functions for PLA/USB/PHY OCP registers
to simplify the code.
