[PATCH v2] arm64: dts: ti: k3-j7200: fix main pinmux range

Range size of 0x2b4 was incorrect since there isn't 173 configurable
pins for muxing. Additionally there is a non-addessable region in the
mapping which requires spliting into two ranges.

main_pmx0 -> 67 pins
main_pmx1 -> 3 pins

Fixes: d361ed88455f ("arm64: dts: ti: Add support for J7200 SoC")

Changes from v1:
* Fixed offsets for new pin ranges
* Correct USB pinmux reference to main_pmx1 from main_pmx0
* Correct pin count in commit message
* Add additional accessible pin to main_pmx1 node
