clk: mediatek: reset: Support nonsequence base offsets of reset registers
The bank offsets are not serial for all reset registers.
For example, there are five infra reset banks for MT8192: 0x120, 0x130,
0x140, 0x150 and 0x730.
To support this,
- Change reg_ofs to rst_bank_ofs which is a pointer to base offsets of
the reset register.
- Add a new define RST_NR_PER_BANK to define reset number for each
reset bank.
