wifi: mt76: mt7921: fix country count limitation for CLC

[ Upstream commit fa6ad88e023ddfa6c5dcdb466d159e89f451e305 ]

Due to the increase in the number of power tables for 6Ghz on CLC,
the variable nr_country is no longer sufficient to represent the
total quantity. Therefore, we have switched to calculating the
length of clc buf to obtain the correct power table. Additionally,
the version number has been incremented to 1.

mt76: mt7921: fix kernel panic by accessing unallocated eeprom.data

The MT7921 driver no longer uses eeprom.data, but the relevant code has not
been removed completely since
commit 16d98b548365 ("mt76: mt7921: rely on mcu_get_nic_capability").
This could result in potential invalid memory access.

To fix the kernel panic issue in mt7921, it is necessary to avoid accessing
unallocated eeprom.data which can lead to invalid memory access.

Furthermore, it is possible to entirely eliminate the
mt7921_mcu_parse_eeprom function and solely depend on
mt7921_mcu_parse_response to divide the RxD header.
