[PATCH] soc/tegra: fuse: Update Tegra234 nvmem keepout list

[Kartik Rajput]

Various Nvidia userspace applications and tests access following fuse
via Fuse nvmem interface:

	* odmid
	* odminfo
	* boot_security_info
	* public_key_hash
	* reserved_odm0
	* reserved_odm1
	* reserved_odm2
	* reserved_odm3
	* reserved_odm4
	* reserved_odm5
	* reserved_odm6
	* reserved_odm7
	* odm_lock
	* pk_h1
	* pk_h2
	* revoke_pk_h0
	* revoke_pk_h1
	* security_mode
	* system_fw_field_ratchet0
	* system_fw_field_ratchet1
	* system_fw_field_ratchet2
	* system_fw_field_ratchet3
	* optin_enable

Update tegra234_fuse_keepouts list to allow reading these fuse from
nvmem sysfs interface.
