[PATCH v3 1/2] arm64: dts: ti: k3-am62a-main: Fix main padcfg length

[Paresh Bhagat]

From: Vibhore Vardhan <vibhore@ti.com>

The main pad configuration register region starts with the register
MAIN_PADCFG_CTRL_MMR_CFG0_PADCONFIG0 with address 0x000f4000 and ends
with the MAIN_PADCFG_CTRL_MMR_CFG0_PADCONFIG150 register with address
0x000f4258, as a result of which, total size of the region is 0x25c
instead of 0x2ac.
