J742S2: Add a new CONFIG_part_variant to differentiate from J784S4
Updating CONFIG_part_variant J784S4->J742S2 so as to differentiate the documentation for any deltas: - linux/Foundational_Components_IPC_J742S2.rst linux/Foundational_Components/IPC/_RPMsg_char_driver.rst J742S2 has 3 C7x instances as compared with 4 in J784S4 - linux/Foundational_Components/Kernel_Drivers/SERDES/SERDES.rst: J742S2 has 3 instances of the SERDES - SERDES0, SERDES1 and SERDES4. SERDES2 is only present in J784S4. Signed-off-by: Aniket Limaye <[email protected]>
