[PATCH] staging: vchiq_arm: Make vchiq_platform_init() static

[Simon Horman <horms@xxxxxxxxxx>]

vchiq_platform_init() is only used in this file so it can be static.

clang-16 with W=1 reports:

 drivers/staging/vc04_services/interface/vchiq_arm/vchiq_arm.c:465:5: error: no previous prototype for function 'vchiq_platform_init' [-Werror,-Wmissing-prototypes]
 int vchiq_platform_init(struct platform_device *pdev, struct vchiq_state *state)
     ^
 drivers/staging/vc04_services/interface/vchiq_arm/vchiq_arm.c:465:1: note: declare 'static' if the function is not intended to be used outside of this translation unit
