Subject: [PATCH v2 0/3] soc: imx8m: Dump higher 64bits UID

i.MX8MP UID is actually 128bits and partitioned into two parts.
The 1st 64bits are at 0x410 and 0x420, and 2nd 64bits are at 0xE00
and 0xE10.

patch 1, 2 is for code cleanup.
patch 3 is for i.MX8MP 128bits support

Marco comments on v1[1] to introduce soc_uid hook.
To do it further, introduce imx8m_soc_prepare/unprepare.

[1]https://lore.kernel.org/all/20250317094518.yf2hbq5sjl7lgfwb@pengutronix.de/

Tested on i.MX8MP/M-EVK

V2:
 Introduce soc_uid hook
 Introduce imx8m_soc_prepare/unprepare

V1: https://lore.kernel.org/all/20250314065225.442717-1-peng.fan@oss.nxp.com/
