Subject: [PATCH v4 04/11] crypto: ccp: move setting PSP master to earlier in the init

Dynamic boost control needs to use platform access symbols
that look for the PSP master as part of initialization.

So move the PSP master before psp_init() so that dynamic boost
control can be initialized properly.

 * Clean up master device if psp_init() failed
