Input: raydium_i2c_ts - fix error codes in raydium_i2c_boot_trigger()

[ Upstream commit 32cf3a610c35cb21e3157f4bbf29d89960e30a36 ]

These functions are supposed to return negative error codes but instead
it returns true on failure and false on success.  The error codes are
eventually propagated back to user space.
